The following categories of sites have been researched: abandoned mining areas, industrial perimeters for the processing of alloys containing radioactive metals, chemical wastes from the chemical fertilizer industry, railways and run- ways that serve to locate radioactive ores, military sites with forgotten radioactive waste, abandoned mines in which chemical and radioactive materials have been deposited, civil and industrial buildings where radioactive materials were used, tourist resorts affected by anthropic and entropic pollution, cases of radioactive floods and heavy metals from food, contamination of external geographic causes.
