Pilots, cabin crew, and astronauts are at more risk of higher doses because of the increased exposure to cosmic rays at altitude. These rays are not harmless but they are unavoidable, and the radiation is at such low levels that its effects are virtually unnoticed. The greatest source of natural radiation for most people is radon.Īdditionally, the Earth is constantly bombarded by cosmic radiation, which includes X-rays. Radioactive material is found naturally in the air, soil, water, rocks, and vegetation. The first person to receive an X-ray for medical purposes was young Eddie McCarthy of Hanover, who fell while skating on the Connecticut River in 1896 and fractured his left wrist.Įveryone on the planet is exposed to a certain amount of radiation as they go about their daily lives.
