Direct physical surveys were noted to be made of radiation levels in the calibratien roca of Building 97 wie radiation levels up to 350 srh. when Co-60 sources were expcsed.

17 Radiatien levels in ucrestricted areas were noted to be less than 0.2 mr/hr at exterior surfaces of the calibratien facility when sources were used.
