Subject:

NRC Inspection No. 70-903/93-01 An announced safety inspection was conducted at the Nuclear Lake site located near Pawling, New York by Mr. J. Roth of this office on January 26, 1993. During this inspection, a radiological survey was performed by the inspector and an NRC contractor (Oak Ridge Institute for Science and Education) in the area of the Nuclear Lake outfall and dam. Soil samples were also taken for analyses.

j The survey results, discussed in the enclosed inspection report, indicate that detectable radiation levels about two times the generally expected background radiation level were found at the surface in some of the excavated / disturbed areas. However, radiation surveys at one meter above the surface did not identify radiation levels above the expected background. Soil samples were obtained from locations that exhibited elevated radiation levels to determine if the elevated readings were the result of naturally occurring radioisotopes, nuclear fallout, or previously i

licensed activities at the site. The soil samples were analyzed for radioisotopes of uranium, i

thorium, americium, radium, and cesium. The uranium, thorium, radium, and cesium isotopes and concentrations present were at the levels expected for naturally occurring materials and nuclear fallout. However, uranium, cesium, and americium (as a decay product of plutonium) were used in previously licensed activities at the site. The concentrations of radioisotopes of those elements present were at levels within NRC guideline values for unrestricted use. Based on the measurements taken, we conclude that there was no safety significance to the radioactivity l

identified.
