Portable Instrumentation for Quantitatively Measuring Radioactive Contamination Levels and for Monitoring the Effectiveness of Decontamination and Decommissioning Activities

摘要

Two completely portable high-resolution germanium diode spectrometer systems are described. These detectors are capable of measuring transuranics, activation products, and fission products, including exp 90 Sr, at sensitivities below the uncontrolled release criteria. The detectors measure x-rays, gamma-rays, or bremsstrahlung radiation as required and have been calibrated for a variety of decontamination and decommissioning scenarios. A description of a new technology for the in-situ determination of exp 90 Sr is given. (ERA citation 08:038545)
