WYOMING DEPARTMENT OF ENVIRONMENTAL QUALITY ~ -'~~~ -~~/ LAND QUALITY DIVISION I~.f~ ~v'OM~a/~./ GUIDELINE N0. 3 V " y 0 /K I ~ RADIOLOGICAL SURVEY / ~G 3~ r g ~3 This, document is a guideline only. Its contents are not to be int r- preted by the applicant or DEQ staff as mandatory. Its preparation is the result of numerous requests from applicants who have expressed a need for a check-list to .assist them in preparation of a comprehensive application containing all required information. ,, ~- a) I. OBJECTIVES The objectives';-of the baseline radiological survey and sampling are to: ~t 1. Establish tlie..nature of the pre-mining radiological envirocmient. 2. Detect and document areas having anomalous radiation. 3. Establish pre-mining concentratiocis.of radiopuclides in the surface materials of the•.Lands to be affected in order to establish a goal for reclamation:, ~. II. GAMMA SURVEY METHODS''- The gamma su;yey should be used 'to determine the pre-mining radiologi- cal environment. iThe followipg methods are recommended. 1. The survey should be conducted using a grid system where. readings are recorded~;at:no greater than 500 foot intervals. Pacing of these-distances is sufficient. - 2. The survey-should also consist of a '=scan method" where readings are noted between-the 500 foot intervals: In this way radiological anomalies igi:ll be, detected. If such anomalies are found, they should be precisely defined as to:location and extent. 3. Readings should be taken with a scintillometer or similar device held approximately three-feet above the ground. 4. Results of the survey should be plotted and isople[hs constructed on a pre-mining topographic map of the survey area..._ See mapping requirements in Guideline 6. The survey grid should be aligned with key control paints to assure similar results if_'the survey is repeated. E. Hinzel/March 1980/Revision 1
