Land sites historically overlain by e.g. tailings storage facilities and mine dumps are potentially contaminated by radioactive residues.

Radio-active gases and particles are released from various sources e.g. tailings storage facilities, contaminated sites and underground ventilation shafts.

Radon exhalation rate, or flux, is the rate of radon release from a source of radon.

PARC Scientific designs and conducts public and environmental radon measurement surveys.

Total radiation dose to workers through inhalation, ingestion and external exposure pathways is assessed in the following scenarios

Elevated radon and external radiation levels exist in work environments containing traces of uranium e.g. underground or surface mines.

The planning phase of a new workplace, such as a mining extension or new mine, must incorporate the radiation safety aspect, and the design will optimise production and safety aspects.
