Radiation Tidbits - Man-made Radiation

Most of the radiation in our daily life comes from the natural environment. However, we also produce radiation in the application of radiation technology. We call this 'man-made radiation'. It may arise from medical exposure, operation of nuclear power plants, nuclear industrial incidents, nuclear weapon tests, etc. Another source of man-made radiation comes from some consumer products which contain radioactive material.
