Detarmination of E 1.0
SUMMARY
E is defined as the av? rage (mean) beta plus the average (mean) gamma energies per disintegration, in Mev, weighted in proportion to the measured activity of each specific radionuclide in the sample.
A calculation of E for reactor coolant should include a minimum of 95% of those isotopes having a half-life greater than 30 minutes.
The average gamma-ray energy per disintegration is a sum of the gamma and x-rays emitted by each nuclide.
The full gamma-ray energies are multiplied by their respective abundance in the decay scheme and summed.
The x-rcy energy which corresponds to the total binding energy in an internal conversion process is added to the total gamma energy.
Also, the x-ray por. tion of the binding energy in an electron capture event is added to the total gamma energy.
The average beta energy per disintegration is obtained by summing one-third of the maximum beta decay energy and all of the conversion and auger electron energy.
The abundance for each decay process is considered before summation of the total beta energy.

4.3 Count the liquid aliquot from Step 4.1 on a GE(Li) detector per Station Chemistry Procedure No.1958.2 and 1958.3 sad record the results on data sheet for isotopes having a half-lives greater than 30 min. Add the sctivities of any gasses still present in the degassed liquid sample to the activities of gasses from Step 4.2.
4.4 Determine the tritium concentration per Station Chemistry Procedure No.1951, Determination of Tritium and record the result on data sheet.
4.5 Determine the concentrations of Sr-89 and SR-90 per Station Chemistry Procedure No.1955, Determination of Strontium and record the results on data sheet.
NOTE:
Analysis may be done by off site laboratory.
4.6 Back calculate the activity of each isotope to the time of initial 89 90 sampling and record on data sheet, i.e. H, Sr and Sr 4.7 From Appendix 1 and Appendix 2 select the average gamma energy (Mev/ dis) and the average beta energy for each isotope present with a half-life greater than 30 min.
Record on data sheet.
4.8 For each isotope having a half-life greater than 30 min, multiply 3
the activity at time of sampling by the average ganh.a energy per disintegration ar.d enter the result in Column 6, multiply the activity at the time of sampling by the average beta energy per J 88 159 2.0 e
