The Radiological Environmental Monitoring Program-includes several '

features that assure high quality results. One feature is the requirement that the contractor analysis laboratory, Teledyne Isotopes Midwest Laboratory (TIML), participate in the U.S. Environmental . .

Protection Agency laboratory crosscheck program. Table E-1'shows the '

crosscheck results obtained between May 1984 and-December 1987.

During the period 333 crosscheck analysis were reported. Ten of the reported results (i.e.-the result plus or minus 2 times the-standard deviation of the result) fell out of the control limits. The control limits were set at the known value plus or minus 1.71 times the standard deviation of the'known value. Of these ten reported results, .

seven of these results were reported during the preoperational program. In 1987, ninety-two crosscheck results were reported, three ,

of these ninety-two fell outside the control limits. The crosscheck

- sample STM-504 for Sr-89, Sr-90 and K fell outside the control limit, j The analytical laboratory explanation for these results states.that= '

milk has a high fat content which.makes analyses difficult, addition ,

of errors to TIML results would put values within-EPA control limits.

The crosscheck sample STW-511 for Ra-228 fell outside the control' limit. The analytical laboratory explanation for these results states  !

TIML results are usually within EPA control limits and the analysis of.

the next sample was within EPA control limits. The crosscheck sample STW-516 for Cr-51 fell outside the control-limit. The analytical laborato,ry explanation for these results states analysis for Cr-51 is difficult and if the error is-taken into consideration then TIML results will fall within EPA control limits.

TLD intercomparisons are not held every. year. Pertinent data from

^

the Seventh International Intercomparison (1984) and the Eighth;

  • International Intercomparison (1985-6) are presented in Table E-2. ->

Reasonable good agreement is seen in each sample. TIML tended to overestimate the known value by about 4%~(+1.3% to-+8.8%).

Another aspect of quality assurance is the in-house: program of -

testing, in which samples spiked with known amounts of radioactive material, or blanks containing no additional radioactive material are submitted for analysis. Table E-3-shows the results:of the in-house spiked sample program. Good agreement between known and reported values was obtained. In all cases except four the error bands of the known and reported values overlapped. In the four cases when they did not overlap, the error was due to reporting a small positive result when the known.value was zero. Table E-4 presents--the-results of the in-house blank sample program. The only activity expected in these j samples is due to naturally-occurring and fallout-related l

radionuclides. No anomalous results were reported. . Table-E-5 shows the acceptance criteria for the spiked samples program.

The results presented in these tables indicated that TIML is capable of routinely performing high quality analysis on environmental samples.
