background radiation
Radiation from cosmic sources, naturally occurring radioactive materials such as granite, and global fallout from nuclear testing
Radiation in the natural human environment originating from cosmic rays and from the naturally radioactive elements of the earth, including those within the human body The level of radioactivity in an area which is produced by sources other than the one of specific interest
Naturally occurring ionising radiation, including cosmic rays and radiation from naturally occurring radioactive materials
The radiation in man's natural environment, including cosmic rays and radiation from the naturally radioactive elements, both outside and inside the bodies of humans and animals It is also called natural radiation Man-made sources of radioactivity contribute to total background radiation levels
The radioactivity in the environment including cosmic rays from space and radiation that exists everywhere-in the air, earth, and man-made materials; people in the U S receive 1,000 to 2,500 microsieverts (100 to 250 millirems) of background radiation per year
the ionizing radiation dose from naturally occurring sources: cosmic rays (gamma rays from outer space), about 30 millirems/year; and radioactive isotopes in the earth's crust, primarily uranium, thorium, radium and potassium, about 30 millirems/year; for an external total dose of about 60 millirems/yr; in addition there is an internal dose from ingestion and inhalation of these naturally occurring radioactive isotopes of about 40 millirems/yr; making for a grand total of about 100 millirems/yr of unavoidable background radiation dose
radiation is around us everyday, including natural radiation, cosmic radiation and radiation in the air we breathe
The natural radiation present in everything surrounding us Examples of this include radiation from the sun's rays, radiation from elements in the ground, and radiation from within our bodies Background radiation varies with location and time, and it can never be reduced to zero
radiation coming from sources other than those being observed
The radiation of man's natural environment originating primarily from the naturally radioactive elements of the earth and from the cosmic rays The term may also mean radiation extraneous to an experiment
Nuclear (or ionizing) radiations arising from within the body and from the surroundings to which individuals are always exposed The main sources of the natural background radiation are potassium-40 in the body, potassium-40 and thorium, uranium, and their decay products (including radium) present in rocks and soil, and cosmic rays
Nuclear (or ionizing) radiation arising from within the body and from the surroundings to which individuals are always exposed (JP 1-02)
Radiation from cosmic sources, naturally occurring radioactive materials, including radon (except as a decay product of source or special nuclear material) and global fallout as it exists in the environment from the testing of nuclear explosive devices The typically quoted average individual exposure from background radiation is 360 millirems or 3 6 millisieverts per year
The naturally occurring nuclear radiation coming from outer space as cosmic radiation, or from naturally occurring radioactive elements such as uranium and radium in the materials of the earth
(see cosmic background radiation)
Radiation that occurs naturally in the environment from cosmic rays and radon or from atomic tests carried out by man
The radiation levels that occur naturally (from other than man-made sources) in the environment Naturally occurring radiation comes from sources such as the sun (cosmic rays), radon from the ground, elements in the soil, water and food
The natural radioactivity in the environment Natural radiation consists of cosmic rays, filtered through the atmosphere from outer space, and radiation from the naturally radioactive elements in the earth (primarily uranium, thorium, radium and potassium) Also known as natural radiation
low-level radiation suffusing the surface of the earth
The ionising radiation in the enviroment to the which we are all exposed It comes from many sources, outer space, the sun, the rocks and soil under our feet, the buildings we live in, the air we breathe, the food we eat, and from our own bodies
