Altitude and latitude can also influence the level of background radiation at any one site. All rocks and soils contain some trace amount of natural radioactivity and can sometimes be ingested or inhaled if disturbed. Radon is a gas that can concentrate indoors and be inhaled, along with its decay products.Altitude and latitude can also influence the level of background radiation at any one site.

What factors affect a person’s level of exposure to background radiation?
The amount of damage that exposure to radiation can cause depends on several factors, including:
- The type of radiation.
- The dose (amount) of radiation.
- How you were exposed, such as through skin contact, swallowing or breathing it in, or having rays pass through your body.
What are 5 sources of background radiation?
Background radiation
- cosmic rays – radiation that reaches the Earth from space.
- rocks and soil – some rocks are radioactive and give off radioactive radon gas.
- living things – plants absorb radioactive materials from the soil and these pass up the food chain.
What determines how much radiation a person is exposed to?
To convert rads to rems, the number of rads is multiplied by a number that reflects the potential for damage caused by a type of radiation. For beta, gamma and X-ray radiation, this number is generally one….Radiation Effects on Humans.
| Dose (rem) | Effects |
|---|---|
| 1000-5000 | Acute illness, early death in days; LD 100/10. |
What causes the most background radiation?
The biggest source of natural background radiation is airborne radon, a radioactive gas that emanates from the ground. Radon and its isotopes, parent radionuclides, and decay products all contribute to an average inhaled dose of 1.26 mSv/a (millisievert per year).
What are the effects of radiation on the environment?
Plants and animals within the affected area take up radioactive particles, and these move through the ecosystem through bioaccumulation. Radiation pollution within waterways also accumulates within fish and other aquatic organisms, and runoff from radiation within the soil provides additional contamination.
What is background radiation quizlet?
background radiation is the low-level radiation that's around us all the time. radiation from space. radiation from space- cosmic rays- come mostly from the sun. radiation from earth (human activity) represents a tiny proportion of the total background radiation.
What are the effects of high radiation exposure on humans?
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.
What is the average background radiation exposure?
Naturally-occurring background radiation is the main source of exposure for most people. Levels typically range from about 1.5 to 3.5 millisievert per year but can be more than 50 mSv/yr.
What determines the quality of radiation?
Radiation quality is determined by the X-ray tube potential selected and the filtration of the X-ray beam. Metal filters are fitted to X-ray tubes to attenuate lower energy photons that are unlikely to reach the image receptor.
