Natural background radiation comes from the ground, building materials, air, food and cosmic rays. Depending on where you live, levels of this type of radiation can vary. Radiation readings above typical background radiation levels may indicate the presence of NORM.

What is the man-made radiation?

Man-made (technogenic) radiation sources are any radiation sources produced by humans. They may being produced for use of their radiation, or for other purposes using the processes taking place in them (e.g., production of electric energy or heat).

What is natural radiation examples?

The composition of the earth's crust is a major source of natural radiation. The main contributors are natural deposits of uranium, potassium and thorium which, in the process of natural decay, will release small amounts of ionizing radiation. Uranium and thorium are found essentially everywhere.
