t Gentlenen:

By letter dated May 23, 1975, you requested an interpretation of 10 CFR Section 20.409, " Notification and Reports to Individual." You indicate

[

that the Commonwealth Edison Company (CE) procedure for implementing the reporting requirements of 10 CFR Parts 19 and 20 at c11 its operating nuclear plants is to provide reports to the individual on termination of exployment only if the actual recorded exposures exceed 25 percent of 10 CFR Part 20. exposure licits.

i You stated that, to avoid the possibility of an unconitored exposure, F

CE, currently requires all persons entering any restricted arca of a nucicar plant to be monitored. Such a raonitoring requirement exceeds the 10 CFR Part 20 minimum monitoring requirements and we cpprove of such a comprehensive monitoring program for individuals. liowever, unless the dose that an individual receives or is likely to receive is assessed prior to entrance into any restricted area in accordance with 10 CFR l-Section 20.202 and a record made of the expected exposure level as a percentage of the 10 CFR Part 20 exposure limits, you cannot use the i

requirements of 10 CFR Section 20.202 to deternine the individual reporting requirenents as specified oy 10 CFR Section 19.13 and 10 CFR Ecetion 20.400.

'Iherefore, all persons nonitored in accordance uith fc.r cougany procedure nust oc notified of their exposure u;.cn ter..:inctio,
