Abstract:

The radioactive contamination problems in gold mining are concentrated in this paper,possible hazard made by radon and radon daughters must be pay great attention.Through the researches for radon gas transfer and permeate mechanism,we proposed appropriate protective measures for different condition.This paper puts forward useful methods of reasonable adjusting the ventilation system in underground mine,setting practicality barrier,using chemical adsorbed mater,and installing high efficiency air filter for controlling the spread and seepage of radon,reducing the concentration of radon and radon daughters in the mine.Routine monitoring in the mine,personnel protection and mine management,also help to reduce workers suffered radiation injury as low as possible.

Key words: Radon and radon daughters, Radiation, Protection, Non-uranium mining
