-Direct Survey'and Removable Contamination Report The direct radiation survey was conducted using Ludlum'Model 19 Micro R meters.

Background was measured as 0.2 uR/hr/.

A Tennelec Modell5100 Proportional counter was used to analyze the smear samples.

The system background was 0.10 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.
