Worker health and safety issues in reinforcing the entombment of the Chernobyl reactor.
The paper provides an overview of current work involving the strengthening of the Sarcophagus over the Chernobyl Nuclear Power Plant destroyed 4th unit. It includes a brief summary of the types of work being performed, the radiological environment, the medical surveillance program, the protective measures being implemented, and the internal and external radiation monitoring program for the workers. Also, it presents a summary of the workplace monitoring data and the internal and external dosimetry data, and estimates of the total effective doses received by the workers during the work. The primary contribution to worker radiation doses was from external exposure. The maximum total effective doses received are 9.2 mSv mo(-1) and 17.4 mSv y(-1).
