, Direct Survey and Removable Contamination Report The direct radiation survey was conducted using Ludlum Model 19 Micro R meters. Background was measured as 0.6 uR/hr/. A Tennelec Model 5100 Proportional counter was used to analyze the smear samples. The system background was .07 cpm for alpha and 0.95 cpm for beta / gamma.
Instrument efficiency was 32% for alpha and 47% for beta / gamma. Counting time on the Tennelee system was 10 minutes. .,
Background Readings Location Reading (uR/hr) Alpha Beta / gamma (DPM/100cm2)
