Description

A study was initiated by the Environmental Radioactivity Laboratory, three years ago, to estimate the various natural radiation components that contribute to the annual effective dose to the population of Camaguey and Ciego de Avila. The natural radioactivity of some building materials commonly used in the above mentioned provinces of Cuba was measured by gamma spectrometry. Typical concentrations, so far encountered, are in the ranges: 47 to 2511 Bq.kg-1 for 40K; 9 to 71 Bq.kg-1 for 226Ra; and 2 to 38 Bq.kg-1 for 232Th. The relationship between the activity concentration and the corresponding annual effective dose is a function of many parameters. The external gamma ray absorbed doses in indoor air, and the corresponding effective dose equivalents in a typical dwelling are presented in this paper
