Description

An assessment of the radiological impact of atmospheric releases from a coal-fired power plant is presented. The atmospheric releases of the major naturally occurring radionuclides have been estimated from analysis of samples of coal and ash as well as from measurements in the stock. The atmospheric concentrations and the environmental transfers of the various radionuclides released were assessed using environmental models. The effective dose equivalents received by the critical group have been calculated for the inhalation, vegetable consumption, and external irradiation pathways. The coal-fired power plant has been assumed to operate for 30 years and the annual effective dose equivalents corresponding to the last year of operation have been estimated; in addition, the variation with time of the annual effective dose equivalents delivered after the power plant ceases operation has been calculated. The doses estimated were found in all cases to be much lower than the regulatory limits. Measurements have also been carried out in air and in vegetation around the plant. The small concentrations obtained are difficult to interpret because of the variability of the natural background

Abstract (French)

On a presente une evaluation de l'impact radiologique des rejets atmospheriques d'une centrale au charbon. Les rejets atmospheriques des principaux radionuclides naturels ont ete evalues a partir d'une analyse d'echantillons de charbon et de cendres, ainsi que de mesures effectuees sur le stock. Les concentrations atmospheriques et les transferts dans l'environnement des differents radionucleides rejetes ont ete evalues a l'aide de modeles de dispersion. Les equivalents de dose effectifs recus par le groupe critique ont ete calcules pour l'inhalation, l'ingestion de legumes, et l'irradiation externe. La duree de fonctionnement de la centrale a ete prevue pour 30 ans. On a evalue les equivalents de dose effectifs recus annuellement par les individus apres arret de la centrale. Les doses estimees ont ete dans tous les cas tres inferieures aux limites reglementaires. Des mesures ont egalement ete faites dans l'atmosphere et sur la vegetation autour de la centrale. Les faibles concentrations obtenues sont difficiles a interpreter a cause de la variabilite de la radioactivite naturelle
