Dade Moeller, an NV5 Company, uses Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) guidance and the Multi-Agency Radiological Survey and Assessment of Materials and Equipment (MARSAME) manual to plan, implement, and evaluate environmental and facility radiological surveys in order to demonstrate compliance with dose or risk-based regulation.
First, we conduct a historical site assessment (HSA) to identify
potential radiological contaminants.
Then, we develop a survey plan
that describes the scanning, sampling, and analytical approach of the
survey; creates data quality objectives; sets derived concentration
guideline levels (DCGLs); identifies survey units and classifications
for impacted areas; and determines the number of sample and/or
measurement locations required in each survey unit.
Finally, we conduct the final site survey and analyze the results following the survey plan. If necessary, we also decontaminate the buildings and equipment.
