What must be done with an old dosimetry badge at the end of each wear period?

At the end of each wear period, it is essential to exchange the dosimetry badge for a new one to ensure accurate monitoring of radiation exposure. Dosimetry badges are designed to measure the amount of ionizing radiation that an individual has been exposed to over a specific period. By exchanging the badge, the facility can monitor exposure levels regularly and maintain compliance with safety regulations and standards.

Keeping track of exposure through periodic badge changes allows for timely assessment of worker safety and any necessary protective measures. This process is crucial in areas where radiation exposure could pose health risks, as it ensures that individuals are not exceeding safe exposure limits.

While other actions might seem viable, like discarding an old badge or reusing it, they compromise safety monitoring and effective radiation exposure management. Retaining old badges for personal records might be helpful from a personal tracking standpoint but does not fulfill the necessary safety protocol that comes with proper dose management. The exchange for a new badge upholds the integrity of exposure assessments and ensures that workers are adequately protected.
