The new "Calculation Guide Mining" is intended to determine the mining-related radiation exposure of members of the public and of workers. It is applicable for the use, decommissioning, remediation, and reuse of mining facilities and installations as well as for the use, remediation, and reuse of land contaminated as a result of mining facilities and installations.
The "Calculation Guide Mining" describes procedures and parameters to determine effective dose indoors, at underground workplaces, and outdoors, as well as exposures caused by consumption of breast milk and locally produced foodstuff. The following exposure pathways are considered: external exposure due to gamma-radiation from the soil, exposure due to inhalation of dust, exposure due to inhalation of radon and its short-lived decay products, exposure from ingestion of breast milk and locally produced foodstuff (drinking water, fish, milk and milk products, meat and meat products, leafy vegetables, other vegetable products), and exposure due to soil ingestion.
In order to account for the background levels of environmental radionuclides, the "Calculation Guide Mining" includes levels of natural background for all relevant environmental media.
