Evaluation of uranium mine atmospheres by measurements of the working level and radon.
Radiation Data Rep 1973 Nov; 14(11):653-657
Using estimates of equilibrium ratios and concentrations of unattached atoms in uranium (7440611) mines, calculations were performed and results presented of the amount of alpha energy per liter of air per working level available to be imparted to the various regions of the respiratory tract. It was discovered that the factor that caused the greatest effect on the alpha energy that could be deposited in the lungs was a change in the unattached fraction of the radon daughters. If the radon (10043922) concentration was used to determine potential exposure, radon to daughter ratios also had a marked effect on the potential alpha energy deposition.
