Direct Survey and Removable Contamination Report Th'e 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 Tennelec system was 10 minutes. ,4 Background Readings Location Reading (uR/hr) Alpha Bata/ gamma (DPM/100cm2 )
