Occupational exposure

Emergency exposure situations require prompt action in order to avoid or reduce adverse consequences. Uncertainty surrounding the ionising radiation types and exposure pathways is likely, particularly in the early stages of an emergency exposure situation. This factsheet provides an overview to protect emergency workers and helpers from exposure to ionising radiation during an emergency.

All occupations undertaken outdoors will result in exposure to ultraviolet radiation (UVR) from the sun. Some occupations, particularly in the manufacturing industry, will be exposed to artificial sources of UVR. Protective measures are advised for workers exposed to UVR in order to minimise potential health risks.

If a worker is pregnant, it is important to evaluate the workplace conditions and implement any necessary additional protective measures.

Exploration workers must be trained in the correct use of borehole logging devices containing radiation sources. Not following procedures may result in exposure to high levels of ionising radiation.

While medical radiation accounts for over 95 per cent of the population’s artificial radiation exposure, the occupational risk for dental workers is very low, with good practice.

While medical radiation accounts for over 95 per cent of the population’s artificial radiation exposure, the occupational risk for medical workers is low, with good practice.

Workers involved in the mining and processing of mineral sands contain radioactive minerals are occupationally exposed to ionising radiation. Current industry exposures are low; regulations, controls and exposure monitoring are required to keep exposures low.

While medical radiation accounts for over 95 per cent of the population’s artificial radiation exposure, the occupational risk for veterinary workers is very low, with good practice. Exposures in veterinary practice can be more variable than in other occupations using ionising radiation.
