he Atomic Energy Conmission has published in the Federal Register on Decenber 3,1970, amendments to 10 CFR Parts 50 and 20 that provide quantitative guidance for light water power reactors proposed to keep'the levels of radioactivity in effluents to unrestricted areas as low as practicable. A copy of 10 CFR Parts 50 and 20 is enclosed for your infonnatied.
We have been reviewing available data from several licensed research facilities and have observed that in general the annual levels of radio-activity in effluents being released are well below the limits specified in the Appendices to 10 CFR Part 20. To assist us in the development of general guidance on applying the "as low as practicable" criterion for research and testing reactors, as stated in Section 20.1(c) of 10 CFR Part 20, this letter is being sent to licensees of research and testing facilities to. obtain information on past experience with respect to the annual levels of radioactivity in effluents released to unrestricted areas from these facilities.
You aie requested to provide the following information:
1.
Se total (measured or estimated) radioactfivity released to unrestricted areas on an annual basis (in curies) as gaseous and liquid effluents and solid wastes.
2.
Identification of the principal radionuclides and the estimated qt.antity of each (in curies) released to the environs in the gaseous and liquid effluents.
3 me maximum (measured or estimated) direct radiation levels and exposures to unrestricted areas 'from (a) direct radiation from the facility, and (b) direct radiation from facility effluents as a result of facility operation. Identify the location of these maxinum values.

A description of onsite and offsite environmental monitoring systems in operation to verify exposures to the general public (including, for exagle, staff and students) in the vicinity of your facility.
5.
A sumnary of the data collected by your environmental monitoring systems since January 1, 1970.
Please include:
(a) The number of sagling locations.
(b) The total number of samples.
(c) The yearly average concentrations of the gross activity and specific radionuclides and total levels of external radiation for each location as well as a description of that location.
(d) An estimate of the minimum level of sensitivity of the monitoring systems.
The above requested infomation should be submitted within 90 days in one signed and 15 additional copies. If any of the above infonnation is already on file in your docket, you may incorporate it in your reply to this letter by specific reference if you wish. Please contact us if you have questions regarding this matter.
Sincerely, Donald J. Skovholt Assistant Director for Reactor Operations Division of Beactor Licensing i
