Joint NRC/EPA Sewage Sludge Radiological Survey: Survey Design & Test Site Results

The objectives of this joint NRC/EPA sewage sludge/ash survey are to:

1. Obtain data on the levels of radioactive materials in sludge and ash at POTWs from across the country.
2. Estimate the extent to which radioactive contamination comes from either NRC/State licensees or naturally-occurring radioactivity.
3. Support potential rulemaking decisions by NRC or EPA, if necessitated by the survey results.
