La radioactivité γ naturelle et ses modifications par l'activité miniére uranifére en bretagne méridionale et vendée, France

Uranium mining has increased the gamma radioactivity by up to 80 times in some areas. The activity also varies, by a factor of 5, with rock composition. The most important problems arise from the dispersion of unshielded radioactive material and the lack of rehabilitation of old mining areas. The continued existence of these problems reveals the inadequacy of existing laws, the past absence of social responsibility and a serious gap in the measures for the protection of public health.
