Abstract

In the present work, external annual radiation doses in human body due to presence of ²²⁶Ra, ²³²Th, ²³⁸U and ⁴⁰K in conventional building materials and by-products from coal power plants which are being used or have the potential for use in buildings and soil in India were calculated in the human body by using GENII radiation dose calculation computer programme (Napier et al., 1988). In the calculations, human beings receive the most radiation dose from building materials from 1.0 × 10^-6 Sv from ⁴⁰K and the least from 2.3 × 10^-11 Sv from ²³²Th. It has been calculated that human beings receive total 6.3 × 10 2 × 10^-7 Sv radiation dose exposure from soil. Data obtained are acceptable in comparison with radiation doses attributable to building materials in OECD countries.

Résumé

Calculs de la dose de radiation dans le corps humain due au contact de matériaux de construction et du sol. La dose de radiation dans le corps human due aux matériaux de construction (utilisés ou potentiellement utilisables) et aux sols en Inde a été calculée grâce au programme GENII (Napier et al., 1988). Nous avons montré qu'elle variait pour les matériaux de construction : de 1,0 × 10^-6 Sv pour ⁴⁰K à 2,3 × 10^-11 Sv pour ²³²Th et que l'irradiation due aux sols était de 6,3 ± 2 × 10^-7 Sv. Ces données sont acceptables en comparaison des doses mesurées pour les matériaux de construction des pays de l'OECD.
