Exposure Attributable to Activities of Authorised Practices
Informing the Board about the extent of radiation exposure in Namibia is a key and central mandate of the NRPA. There are different sources of radiation exposures leading to radiation exposure of the workers and the public.
Workers and the public are liable to incur radiation exposure above normal background level due to the activities of authorised practises.
The NRPA has a programme in place to ensure that workers are subject to routine assessment of the radiation exposure while the exposure of others workers and that of the public is determined on the basis of workplace and area monitoring.
The purpose of the monitoring programmes
- To demonstrating compliance with the regulatory limit (20mSv/a for workers and 1mSva for members of the public;
- Establishing baseline data and reference levels to optimise the exposure;
- Confirming good working practices;
- Providing information about conditions in the workplace;
- Providing information about the magnitude of potential risks as a result of exposure resulting from these practices.
