U.S. EPA COUNTS PER MINUTE (CPM) FOR SUPERFUND ELECTRONIC CALCULATOR
U.S. EPA COUNTS PER MINUTE (CPM) FOR SUPERFUND ELECTRONIC CALCULATOR
U.S. EPA, 2025

EPA developed the CPM electronic calculator to help risk assessors, RPMs, and others involved with risk assessment and decision-making at radioactively contaminated sites. The CPM electronic calculator provides a method for correlating real-time survey results, which are often expressed as counts per minute, to contaminant concentrations that are more typically expressed in pCi/g or pCi/m2, at Superfund sites (those regulated under CERCLA). The CPM calculator intends to facilitate more real-time measurements within a Superfund response framework. The CPM calculator may also standardize the process of converting lab data to real-time measurements. It will thus lessen the amount of lab sampling that is needed for site characterization and confirmation surveys, but it will not remove the need for sampling. https://epa-cpm.ornl.gov/index.html
