Abstract

The rural Municipality of Vinaninkarena (19°57'21.9"S; 47°02'22.1"E) has abandoned uranium site, located in the Vatovory village. The uranium mining has been exploited by CEA (Commissariat à l'Energie Atomique) French Company between 1946 and 1952. After closing of exploitation, the hazards of internal and external exposures persist, because most of the populations are not aware of the harmfulness effects of the ionizing radiations. In fact, this present work enable to compare the results of the mean annual effective dose received by the population in the outdoor and the indoor of the studied areas using direct method TLD dosimeters and IdentiFinder; and the indirect method from the soil radioactivity measurement for the external exposure. The obtained results of annual effective dose have been compared with the three international (UNSCEAR 2000, BSS 115, and GS Part 3 Interim), and the national (Radiation Protection Regulation in Madagascar) references values. It has been established that the direct method using Thermoluminescent Dosimeters (TLDs) and IdentiFinder are shown more efficient of the received dose assessment compared to the indirect method. In addition, the dose rate values provided by the IdentiFinder spectrometer are relatively similar to the value indicated by the individual TLDs using the correlation plot.
