Radon dose calculation methodology for underground workers in the Czech Republic.

Area of Science:

• Environmental Science
• Occupational Health
• Radiation Physics

Background:

• Workers in caves, including those for speleotherapy, face potential exposure to natural ionising radiation.
• Accurate assessment of radiation levels in underground workplaces is essential for worker safety.

Purpose of the Study:

• To classify irradiation levels from natural sources for workers in caves.
• To establish a procedure for determining effective dose in underground environments.
• To review existing methods for evaluating lung irradiation.

Main Methods:

• Integral measurements of radon volume activity and worker time spent in caves.
• Continuous and integral measurements of radon decay products.
• Analysis of cave atmosphere characteristics, including climatic parameters and aerosol spectra.

Main Results:

• A defined procedure for calculating effective dose from radon exposure in caves.
• Experimental data on cave atmosphere parameters were collected.
• Literature review on lung irradiation evaluation methods was conducted.

Conclusions:

• The developed methodology provides a basis for accurate dose assessment for workers in caves.
• This approach is applicable to various underground workplaces.
• Understanding radon exposure is key to managing occupational health risks in subterranean environments.
