The exposure of the population to both cosmic and nuclear radiation, particle accelerators, atomic physics institutes, nuclear weapon experiments in specially designed polygons, radioactive waste deposits, the use of radioisotopes in industrial or medical activities is carefully monitored, and as a result of major nuclear events such as Chernobyl, Tokaimura, Three Miles Island, Wind Scale and Fukushima, environmental dosimeter has gained unprecedented expansion and development. The monitoring of the natural radioactive level aims at achieving more practical objectives that are most often due to legal obligations or international commitments. The portal at the old iron base on a steel platform signaled a load of recyclable metallic materials as a radioactive suspect. The 226Ra isotope was identified. A criminal case was filed for the offense of "non-observance of the nuclear material or other radioactive material regime".
