e 3.0 ENVIRONMENTAL RADIOLOGICAL MONITORING PROGRAM 3.1 Program Design and Data Interpretation The purpose of the Environmental Radiological Monitoring Program at the Duane Arnold Energy Center (DAEC) is to assess the impact of the plant on its environment. For this purpose, samples are collected from the air,

, terrestrial, and aquatic environments and analyzed for radioactive content. In addition, ambient gamma radiation levels are monitored by s

thermoluminescent dosimeters (TLD's).

Sources of environmental radiation include the following:

(1) natural background radiation arising from cosmic rays and primordial radionuclides; (2) fallout from atmospheric nuclear detonations; (3) releases from nuclear power plants.

In interpreting the data, effects due to the DAEC operation must be distinguished from those due to other sources, t

A major interpretive aid in assessment of these effects is the design of the monitoring program at the DAEC which is based on the indicator-control concept. Most types of sanples are collected both at indicator locations (nearby, downwind, or dosnstream). and at control locations (distant, upwind, or upstream). A station effect would be indicated if the radia-tian level'at an indicator location was significantly larger than that at the control location. The difference would have to be greater than could be accounted for by typical fluctuations in radiation levels arising from other sources.

An additional interpretive technique involves analyses for specific radionuclides present in the environmental samples collected from the DAEC site. The DAEC's monitoring program includes analyses for strontium-89, strontium-90, and iodine-131, which are fission products, and tritium, which is produced by cosmic rays, atmospheric nuclear detonations, and ~

also by nuclear power plants. Most samples are also analyzed for gamma-emitting isotopes with results for the following ' groups quantified:

zirconium-95, cesium-137, and cerium-144. These three gamma-emitting isotopes were selected ~ as radiological impact indicators because of the different characteristic proportions in which they appear in the fission 3

l m _

L product mix produced by a nuclear reactor and that produced by a nuclear detonation. Each of the three isotopes is produced in roughly equivalent amounts by a reactor: each constitutes about 10% of the total activity of fission products 10 days after reactor shutdown. On the other hand, 10 days after a nuclear explosion, the contributions of zirconium-95, cerium

-144, and cesium-137 to the activity of the retulting debris are in the approximate ratio 4:1:0.03 (Eisenbud, 1963).

The other group quantified consists of niobium-95, ruthenium-103, and

-106, cesium-134, barium-lanthanum-140, and cerium-141. These isotopes are released in small quantities by nuclear power plants, but to date their major source of injection into the general environment has been atmospheric nuclear testing. Nuclides of the next group, manganese-54, cobalt-58, and -60, and zinc-65, are activation products and arise from activation of corrosion products. They are typical components of nuclear power plant's effluents, but are not produced in significant qpantities by nuclear detonations. Nuclides of the final group, beryllium-7, which is of cosmogenic origin, and potassium-40, a naturally-occuring isotope, were chosen as calibration monitors and should not be considered radio-logical impact indicators.

Characteristic properties of isotopes quantified in gamma-spectroscopic analyses are presented in . Table 5.1. Other means of distinguishing sources of environmental radiation can be employed in interpreting the data. Current radiation levels can be compared with previous levels, including those measured before the Plant became operational. Results of the -DAEC's Monitoring Program can be related to those obtained in other parts of the world. Finally, results can be related to events known to cause elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations.

3.2 Program Description The sampling and analysis schedule for the environmental radiological monitoring program at the DAEC is summarized in Table 5.2 and is briefly reviewed below. Table 5.3 defines the sampling location codes used in Table 5.2 and specifies for each location its type (indicator oc control) and its distance, direction, and sector relative to the reactor site.

The types of samples collected at each location and the frequency of collections are presented in Table 5.4 using codes defined in Table 5.5.

To monitor the air environment, airborne particulates are collected on membrane filters by continuous pumping at sixteen locations. Also, airborne iodine is collected by continuous pumping through charcoal filters at eight of .these locations. Twelve of the sixteen locations 4

\

are indicators and four are controls (D-1, 0-2, 0-12, and 0-13). Filters ,

are changed and counted weekly. Particulate filters are analyzed for '

gross beta activity. If gross beta activity exceeds 10 pCi/m3, gamma isotopic analysis is performed. Quarterly composites of airborne parti-culates from each location are analyzed for strontium-89, strontium-90, and gamma scanned on a germanium detector.

Charcoal filters are analyzed for I-131 on two composites: one from locations D-8, D-12, and D-14, and one from locations D-4, D-5, D-7, 0-11, and 0-15. If iodine-131 is detected, each cartridge is analyzed individually.

Ambient gamma radiation is monitored at fifteen (15) air sampling loca-tions. In addition, gamma radiation is monitored at forty-eight (48) special locations: sixteen (16) in a circle within 0.5 mi radius of the DAEC stack; sixteen (16) in 22.5* sectors within 1 mi of the DAEC stack; and sixteen (16) in 22.5* sectors between 1 and 3 miles of the DAEC stack. The sensors are placed in quintuplicate at each location and are exchanged and analyzed monthly. Additionally, a second set of dosimeters is placed at the same locations and exchanged and analyzed annually.

Precipitation samples are collected monthly from one location and analyzed for gross beta and tritium.

Milk samples are collected monthly from nine locations during the non-grazing season, October through April, and weekly during the grazing season, May 1 through September 30. Two of the locations are control (0-102 and D-105) and the rest are indicators. During the non-grazing season, milk samples from all indicator and all control locations are composited separately, and analyzed for iodine-131. If the level of iodine-131 in any of the composites equals or exceeds 2.4 pCi/1, the milk is resampled from each location and analyzed individually for iodine-131.

During the grazing season, milk from five locations within a five mile radius of the DAEC stack (D-63, D-93, D-94, D-101, and D-106) is analyzed individually for iodine-131. Milk from two locations within a ten mile radius of the DAEC stack (D-72 end D-96) and from two control locations (0-102 and D-105) are composited separately and also analyzed for iodine-131. If the level of iodine-131 in any of the composites equals or exceeds 2.4 pCi/1, the milk is resampled and analyzed individually for iodine-131. In additicn, inonthly composites of weekly collections from each location are analyzed for strontium-89, strontium-90, elemental calcium, and gamma-emitting isotopes.

For additional monitoring of the terrestrial environment, grain, hay, and broad leaf natural vegetation samples are collected annually from eleven locations: two controls (D-102 and D-105) and nine indicators (D-57, D-58, D-63, D-72, D-93, 0-94, D-96, 0-101, and 0-106). Grain and hay are analyzed for gamma-emitting isotopes and broad leaf vegetation is ana-lyzed rcr iodine-131. Meat and poultry are collected annually during 5 - - - - - - - - .

or immediately following a grazing period from animals fed on crops grown within and outside ten miles of DAEC. The samples are analyzed for gamma-emitting isotopes. A wildlife sample is collected semi-annually within a 10 mile radius of DAEC and analyzed for gi.ma-emitting isotopes.

Also, potable ground water is collected at least every two hours from a treated municipal water system (D-53), daily from the inlet to the municipal water treatment system (D-54), and monthly from five additional ground water locations (D-55, D-57, 0-58, D-59, and 0-60). The samples are composited into monthly and quarterly composites for each location.

Gross beta analysis is performed on all monthly composites. If gross beta activity exceeds 10 pCi/1, gamma isotopic, strontium-89, and stron-tium-90 analyses are performed. Strontium-89, strontium-90 and tritium analyses are performed on all quarterly composites.

Soil samples are collected three times per year at two control locations (0-102 and D-105) and eleven indicator locations (D-15, D-16, D-57, D-58, 0-63, D-72, D-93, 0-94, D-96, D-101, and D-106). The samples are analyzed for strontium-90 and gamma-emitting isotopes.

Surf ace water is collected monthly from seven river anc pond locations, two control (D-49 and D-73) and five indicator (D-50, 0-51, D-52, 0-99, and D-103). All monthly samples are analyzed for gross beta and gamma-emitting isotopes. If gross beta activity exceeds 10 pCi/l the samples are analyzed for strontium-89 and strontium-90. Tritium, strontium-89, and strontium-90 analyses are performed on quarterly composites from each location.

The aquatic environment is also monitored by upstream and downstream (D-49 and D-61) quarterly collections of aquatic biota (periphyton) and semi-annual collections of fish and river sediment. River sediment is also collected at the plant's intake and discharge (D-50 and D-51). Fish and aquatic biota are analyzed for gamma-emitting isotopes. River sediment is analyzed for strontium-90 and gamma-emitting isotopes.

3.3 Program Execution The program was executed as described in the preceding section with the following exceptions:

(1) TLD data for several locations was not available for some months because TLDs were stolen, destroyed by either animals or vandals, or lost in the field. The lost TLDs are listed below.

Location Month Lost D-13,36 January 0-13 February D-27,44 March D-9,14,44 April D-22,42,76,84 May 0-1,45,78,83 June D-42 October D-91 November D-13 December 6

(2) No annual TLD data was available for locations 0-13, 0-16, and D-42 because thev were lost in the field.

(3) No air particulates were available for analyses from locations D-1 thru D-14 and D-16 for the collection period ending 11 83 because they were lost in transit.

(4) No charcoal cartridges were available for analyses from loca-tions 0-4, D-5, D-7, D-8, D-11, D-12, and D-14, for the col-lection period ending 11-10-83 because they were lost in transit.

(5) No air particulates were available for analyses from locations D-9 and D-16 for the collection periods ending 12-22 and 12-29-83 because pump vanes were frozen.

(6) No air particulate and charcoal were availatle for analyses from location D-14 for the collection period ending 12-09-83 because of blown fuse.

(7) No air particulates and charcoal were available for analyses from location D-15 for the collection period from 10-05 thru 12-09-83 because electricity was shut off, due to relocation of sampler.

(8) .No air particulate was available for analysis from location D-16 for the collection period ending 8-10-83 because electri-city was shut off.

(9) No well water was collected from location D-60 in January 1983 because the well was shut off.

3.4 Laboratory Procedures All strontium-89, strontium-90, and iodine-131 analyses in milk were made by using a sensitive radiochemical procedure which involves separation of the element of interest by use of ar. ion-exchange resin and subsequent beta counting.

All gamma-spectroscopic analyses were performed with high resolution germanium detectors. Levels of iodine-131 in natural vegetation were determined by germanium spectrometry. Levels of airborne iodine-131 in charcoal samples were measured by germanium spectrometry.

Tritium levels were determined by the liquid scintillation technique.

Analytical Procedures used by the TIML are specified in detail elsewhere (HES, 1981), Procedures are based on those prescribed by the National 7

Center for Radiological Health of the U.S. Public Health Service (U. S. !

Public Health Service,1967) and by the Health and Safety Laboratory of '

the U. S. Atomic Energy Commission (U. S. Atomic Energy Commission, 1972).

4 Details of TIML's QA Program are presented elsewhere (Hazleton Envi-i ronmental Sciences,1982 under revision). The TIML QA Program includes participation in laboratory intercomparison (crosscheck) programs.

Results obtained in crosscheck programs are presented in Appendix A.

3.5 Program Modifications Effective in July, 1983, strontium-89 and strontium-90 analyses were performed on all quarterly composites of surface water and ground water.

Composites of the first and second quarters of 1983 were retrieved from storage and analyzed.

Also, in July,1983, gamma isotopic analyses for milk samples were performed on monthly composites rather than on individual weekly samples.

4.0 RESULTS AND DISCUSSION All of the scheduled collections and analyses were made except those listed in Table 5.6.

All results are summarized in Table 5.7 in a format recommended by the Nuclear Regulatory Commission in Regulatory Guide 4.8. For each type of analysis of each sampled medium, this table lists the mean and range of all indicator and control locations. The locations with the highest mean and range are also shown.

The tabulated results of all measurements made in 1983 are not included in this section, although references to these results will be made in the discus-sion. The complete tabulation of the 1983 results is contained in Part II of the 1983 annual report on the Environmental Radiological Monitoring Program for the Duane Arnold Energy Center.

4.1 The Effect of Chinese Atmospheric Nuclear Detonation There were no reported atmospheric nuclear tests in 1983. The last reported test was conducted by the People's Republic of China on 16 October 1980. The reported yield was in the 200 kiloton to 1 megaton range.

4.2 Proaram Findinas Results obtained show background levels of radioactivity in the environ-mental samples collected in 1983. The residual effect of previous nuclear tests was detected in some of the milk, vegetation, and soil samples (strontium-90 and cesium-137). No Plant effect was indicated.

Airborne Particulates The average annual gross beta activity in airoorne particulates was nearly identical at both indicator and control locations (0.022 and 0.024 pCi/m3, respectively) and was about the same as in 1982 (0.026 pCi/m3).

-The highest averages for gross beta were for the month of December and the fourth quarter.

The spring peak, which is usually observed in April - May (second quarter),

was not evident in 1983.

9

This peak has been observed almost annually (1976,1979 and 1980 were also exceptions) for many years (Wilson et al.,1969). The spring peak has been attributed to fallout of nuclides from the stratosphere (Gold et al.,1964).

Two pieces of evidence indicate conclusively that the elevated observed activity during the fourth quarter was not attributable to the Plant. In the first place, elevated activity of similar size occurred simultaneously at both the indicator and control locations. Secondly, a similar pattern was observed at other nuclear power plant locations in the Midwest.

Strontium-89 and -90 levels were below their respective LLDs in all samples.

Except for beryllium-7, which is produced continuously in the upper atmos-phere by cosmic-ray interactions (Arnold and Al-Salih,1955), all other gamma-emitting isotopes were below their respective LLD levels. None of the activities detected were attributable to the Plant operation.

Airborne Iodine Airborne iodine-131 results .were below the detection limits of 0.006 pCi/m3 for all indicator locations and below 0.01 pCi/m3 for all control locations.

Ambient Radiation (TLD's)

The mean monthly doses as measured by the monthly TLDs measured 3.610.6 mR/30 days at indicator locations and 3.4i0.5 mR/30 days at control locations. Annual TLDs, normalized .to 30 days, yielded 4.610.5 mR/30 days and 4.0 i0.8 mR/30 days for indicator and control locations, respec-tively. Since standard deviations were larger than the differences, the differences are not statistically significant. No Plant effect was indicated.

Precipitation Gross beta levels varied widely indicating the relationship between the level of activity and amount of rainf all, and ranged from 2.3 to 32.4 pCi/1. Tritium was below the LLD'of 330 pCi/l in all samples. No Plant effect was indicated.

10

l Milk Iodine-131 results were below the detection limit of 0.4 pCi/l in all samples.

Strontium-89 was below the LLO level of 5 pCi/l in all samples.

Strontium-90' activity was detected in all samples and was nearly identi-cal at both indicator locations (2.3 pCi/1) and control locations (2.4 pCi/1), ranging froa 0.7 pCi/l to 6.3 pCi/1. Tne activity and range were similar to those observed in 1980,1981, and 1982. Strontium-90 levels in this range are attributable to worldwide fallout from previous atmos-pheric nuclear tests, and reflect the long half-life (28.64 years) of this isotope. Cesium-137 results were below the LLD level of 15 pCi/l in all samples. Lesium-137 is also a long-lived component (with a half-life of 30.24 years) of worldwide fallout and is found in the environment in trace amounts. The apparent absence of the effect of the latest nuclear test (October 1980) on strontium-90 and cesium-137 results is consistent with the low initial production of these isotopes in nuclear explosions (Eisenbud,1963). No other gamma-emitting isotopes, except potassium-40, were detected in any milk samples. This is consistent with the finding of the National Center for Radiological Health that most radiocontami-nants in feed do not find their way into milk due to the selective metabolism of the cow. The common exceptions are radioisotopes of potassium, cesium, strontium, barium, and iodine (National Center for Radiological Health, 1968). Calcium was measured in all samples and ranged from 0.8 g/l to 1.6 g/1, averaging 1.2 g/1. The measured concen-trations of calcium are in agreement with the published national values (National Center for Radiological Health, 1968).

In summary, the milk data for 1983 show no radiological effects of the Plant operation, but the presence of strontium-90 in milk samples does exhibit a long range residual effect of previous atmospheric nuclear tests.

Ground Water Ground water samples were analyzed monthly for gross beta activity.

Quarterly composites were also analyzed for gross beta (for the first and second quarters only) and for tritium. The annual mean for gross beta in monthly measurements (3.3 pCi/1) was similar to the mean in quarterly measurements (3.5 pC1/1). The location with the highest mean, 6.1 pCi/1, was D-59, Frantz Cottage, 0.5 mi distant from DAEC. The levels were similar to those observed in 1980, 1981 and 1982. Tritium was below the LLD level of 330 pCi/l in all samples. There was no indication of a Plant effect.

11

Meat and Poultry In meat and poultry, naturally-occurring potassium-40 was the only gamma-emitting isotope detected. All other gamma-emitting isotopes were below their respective LLD's. Thus, no Plant effect was indicated.

Wildlife In wildlife samples (opossum and woodchuck), collected on the site, the only gamma-emitting isotope detected was naturally-occurring potassium-40.

The average activity was 3.42 pCi/g wet weight. No Plant effect was indicated.

Vegetation Iodine-131 results in broad leaf vegetation were below the LLD level of 0.096 pCi/g wet weight in all samples. In corn, strontium-90 activity was below the LLD level of 0.006 pCi/g wet weight in all samples. In hay, strontium-90 was detected in all samples and was slightly higher at indicator locations (0.179 pCi/g wet weight) than at control locations (0.145 pCi/g wet weight). In soy beans and oats, strontium-90 was also detected in all samples and was also slightly higher at indicator locations (0.021 pCi/g wet weight) than at control (0.014 pCi/g wet weight) loca-tions. Presence of strontium-90 in hay and soy beans is attributable to the fallout from nuclear tests. No Plant effect was indicated.

Except for potassium-40, which was observed in all samples, all other gamma-emitting isotopes were below detection limits in all samples. No Plant effect was indicated.

Soil Strontium-90 was detected in all soil samples and averaged 0.09 pCi/g dry weight for indicator locations and 0.10 pCi/g dry weight for control locations. The difference is not statistically significant.

The predominant gamma-emitting isotope detected was potassium-40. The measured activity was nearly identical at both indicator and control locations (11.47 pCi/g dry weight and 11.56 pCi/g dry weight, respec-tively).

Cesium-137 was detected in all samples and the activity was similar at both the indicator locations (0.34 pCi/g dry weight) and the control locations (0.40 pCi/g dry weight).

Presence of strontium-90 and cesium-137 in soil is attributable to the f allout from previous nuclear tests in the atmosphere. No Plant effect was indicated.

Surface Water Mean gross beta activity was slightly higher at indicator locations (6.2 pCi/1) than at the control locations (3.3 pCi/l) and was similar to that observed in 1980, 1981, and 1982. The difference is not statistically significant. Tritium was below the LLD level of 330 pCi/l in all saniples.

Strontium -89 and strontium-90 were below the LLD levels of 10 pCi/l and 2.0 pCi/1, respectively, in all samples. No gamma-emitting isotopes were detected in any of the samples analyzed. No Plant effect on surface water was indicated.

Fish All gamma-emitting isotopes, except naturally-occuring potassium-40, in edible portions were below detection limits. No Plant effect on fish was indicated.

Periphyton Periphyton samples were collected in February, May, August, and November.

All gamma-emitting isotopes, except potassium-40, were below detection limits. No Plant effect was indicated.

River Sediments River sediments were collected in May and November and analyzed for strontium-90 and gamma-emitting isotopes. Strontium-90 results were below the.LLD level of 0.015 pCi/g dry weight in all samples. All gamma-emitting isotopes, except potassium-40, were below detection limits in all samples. There was no indication of Plant effect.

A-1

Appendix A Crosscheck Prooram Results Teledyne Isotopes Midwest Laboratories (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscneck) programs since the formulation of its cuality control program in December 1971. These programs are operated by agencies which supply environmental-type samoles (e.g., milk or water) containing concentrations of radionuclides known to the issuing ' agency but not to participant laboratories. The purpose of such a program is to provide an independent check on the laboratory's analytical

~

procedures and to alert it to any possible problems.

Participant laboratories measure the concentrations of specified radionuclides and report them to the issuing acency. Several months later, the agency

- reports.the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procecures used.

The results in Table A-1 were obtained through participation in the environ-mental sample crosscheck program for milk and water samoles during the period 1980 through 1983. This program has been conducted by the U. S. Environmental Protection Agency Intercomoarison and Calibraticn Section, Quality Assurance Branch, Environmental Monitoring and Suoport Laboratory, Las Vegas,- Nevada.

The results in Table A-2 we: e obtained for thermoluminescent dosimeters (TLD's) during the period 1976, ;1977, 1979, 1980, and 1981 through parti-cipation in the Second, Third, Fourth, and Fifth International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2.

Appendix 8 Data Reporting Conventions I

t B-1

Data Reporting Conventions 1.0. All activities are decay corrected to collection time.

2.0. Single Measurements Each single measurement is reported as follows:

xis where x = value of the measurement; s = 2a counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is found to be below the lower limit of detection L it is reported as

<L .

where L = is the lower limit of detection based on 4.660 uncertainty-for a background sample.

3.0. _Duolicate Analyses 3.1. Individual results: x1 s1 x2 sg Reported result: x s where x = (1/2) (x1 + x2) s = (1/2) fs2+s2 3.2. Individual results: <L1

<L2 Reported result: <L where L = lower of L1 and Lg 3.3. Individual results: x s

<L Reported result: x i s if x < L:

Appendix A Crosscheck Program Results A-1

Appendix A Crosscheck Program Results Teledyne Isotopes Midwest Laboratories (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental-type samples (e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on the laboratory's analytical

-procedures and to alert it to any possible problems.

Participant laboratories measure the concentrations of specified radionuclides and report them to the issuing acency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.

The results in Table A-1 were obtained through participation in the environ-mental sample crosscheck program for milk and water samoles during the period 1980 through 1983. This program has been conducted by the U. S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada.

The results in Table A-2 were obtained for thermoluminescent dosimeters (TLD's) durina the period 1976, 1977, 1979, 1980, and 1981 through parti-cipation in the Second, Third, Fourth, and Fifth International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2.

4 Data Reporting Conventions "

'l.0. All activities are decay Corrected to Collection time.

2.0. Single Measurements Each single measurement is reported as follows:

x s where x = value of the measurement; s = 2Cfcounting uncertainty (corresponding to the 95% confidence level).

-In cases where the activity is found to be below the lower limit of detection L it is reported as

<L .

where L = is the lower limit of detection based on 4.66a uncertainty for a background sample.

3.0. Duplicate Analyses 3.1. Individual results: x1 s1 x2 t s2 Reported result: xis where x = (1/2) (x1 + x2) s=(1/2)ks +s 3.2. Individual results: <ll

<L2 Resorted result: <L vihere L = lower of L1 and L2 3.3. Individual results: xts

<L Reported result: x s if x < L;

<L otherwise B-2

o' i

4.0. Comoutation of Averaces and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averagec; for example, an annual standard deviation would_not be the average of quarterly standard deviations. The average x and standard deviations of a set of n numbers x1, x2, . . . xn are defined as follows:

x=fIx 3, I(x-x)2 n-1 4.2 Values below the highest lower limit of detection are not inclucea in the average.

4.3 If all of the values in the averaging group are less than the highest LLD, the highest LLD is reported.

4.4 If all but one of the values are less than the hignest LLD. tne single value x and associated two sigma error is reportea.

4.5. In rounding off, the following rules are followed:

4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged. As an example,11.443 is rounded off to 11.24.

4.5.2 If the figure following those to be retained is greater than 5, the figure is dropped, and the last retained figure is raised by 1. As an example, 11.446 is rounded off to 11.45.

4.5.3. If the figure following those to be retained is 5, and if there are no figures other than zeros beyond the five, tne figure 5 is dropped, and the last-place figure retainec is increased by one if it is an odd number or it is kept unchangea if an even number. As an example, 11.435 is rounded off to 11.44, wnile 11.425 is rounded off to 11.12.
