Calibration of Radiation Detectors for Monitoring and Decontamination of Radioactive Surface Contamination

Abstract

This study presents a systematic approach for managing radioactive surface contamination and evaluating the effectiveness of decontamination procedures. The methodology involves the calibration of three distinct radiation detectors: Monitor E, Monitor S, and NE BP1/4, followed by the identification of the contamination source. Instrumental monitoring was integrated with smear testing to assess the efficacy of surface decontamination. This was performed by wiping the contaminated areas with specialized filter papers and measuring the residual radioactivity. The results demonstrated successful surface decontamination; subsequently, the generated radioactive waste was collected and disposed of in compliance with established radiological safety guidelines. Waste disposal procedures were initiated once the total accumulated activity reached the regulatory limit of 370 kBq, as determined by the filter paper measurements.
