What I did here

Provided health physics coverage in support of initial site characterization in accordance with MARSSIM guidelines. Performed radiological screening of surfaces for alpha/beta activity via (Shonka) cart mounted gas flow position sensitive proportional counter (PSPC) integrated with a survey information management system (SIMS). Performed concurrent gamma measurement with both a GM detector for general area dose rates and a NaI detector coupled with a single channel analyzer.
