What is background radiation? All living things are exposed to natural ionising radiation from the environment. We normally do not think about this exposure to radiation because it comes from things we accept in our everyday lives.
Background Radiation: Definition, Causes & Examples. Lesson Transcript. Instructor Erin Ryan. This lesson will define background radiation, explain how it is measured, discuss some of the...
Jul 5, 2023 · Background radiation refers to exposure to ionizing radiation in day-to-day life, excluding occupational exposures. It is measured in millisieverts (mSv). Ionizing radiation occurs naturally in the environment 1,2: radioactive gas (e.g. radon, thoron): 0.2-2.2 mSv/year. external terrestrial (e.g. building materials): 0.3-1 mSv/year.
Background radiation varies from place to place and over time, depending on the amount of naturally-occurring radioactive elements in soil, water and air. Weather conditions also affect radiation levels, as snow cover may shield these elements, and radioactive particulates can wash out of the air during rain storms.
Jul 30, 2013 · Humans are always exposed to a background radiation spread of radioactive nuclei in the air, soil, rock, water, and building materials. The amount of background radiation is different in terms of height, the amount of the nuclei present in the soil, and the geographical conditions of different regions.

Background Radiation. We are all exposed to a small amount of radiation in our daily lives. This background radiation comes from naturally occurring sources and from human-produced radiation. Exposure to x-rays and nuclear medicine isotopes, ground sources, and cosmic radiation account for almost half of the background exposure of the average ...
Background Radiation. Background radiation surrounds us at all times—it is everywhere. Since the earth was formed and life developed, all life on earth has been exposed to ionizing radiation*. This fact sheet addresses the baseline sources of back-ground ionizing radiation.
