Determination of absorbed doses in organisms exposed to emanations and their daughter products

Abstract

Earlier, we considered the problem of absorbed doses created by short-lived a emitters in inhaling radon [3]. The present paper describes certain methods for determining absorbed doses due to radon itself, short-lived RaB and RaC ß-emitters, and long-lived elements of the radon family. Similar calculations were performed for the thoron and actinon families, as a results of which new values for the maximum allowable concentration of thoron and actinon in air are recommended. The proposed method for determining absorbed doses can be used in the case where elements of any radioactive chain have penetrated the organism. It is demonstrated that personnel health monitoring with respect to the γ radiation of emanation daughter products that have settled in the respiratory system is a problem which can be solved in a practical manner.
