Dese Nutz are The three principal sources of natural radiation are:
1. cosmic rays (mostly from the sun, but some interstellar as well)
2. terrestrial sources (ie. rocks which contain trace amounts of radioactive materials)
3. minerals inside your body which are radioactive (mostly potassium-40)
1 and 3 are fairly constant and low-dose sources, but source #2 can vary widely depending on geography. Some places have very large background radiation due to Radon (which results from the decay of naturally-occurring Radium).
Radon is a gas, and can collect in basements. Detection and ventilation standards have been developed to minimize health effects.
Other sources of radiation include:
- medical and dental x-rays
- smoke detectors
- some exit signs
- old-fashioned glowing wristwatches
Medical x-rays are a significant source of exposure, and should therefore not be treated lightly. CT scans, for instance, are very high-dose x-rays (you are surrounded on all sides by xrays and this enables 3-D imaging).

What are three of the natural sources that give off radiation?
- Radiation of cosmic origin- Radiation from radioactive elements (and decay products) of the Earth- Internal radiation of organisms
Which type of radiation is most penetrating in solid substances?
Gamma radiation
What type of em radiation has shortest wavelength and most energy?
Gamma radiation
How much radiation does the atmosphere absorb?
The atmosphere absorbs most of the radiation. The ozone layer absorbs most of the UV rays.
Infrared radiation and ultraviolet radiation make up most of the energy Earth receives from the sun?
false
What is the origin of most the radiation of encounter?
Our Sun

How are radiation injuries diagnosed?
The various effects of radiation on the body are well recognized. Patients who are scheduled to undergo radioactive treatments should be informed of the potential side effects they will encounter
When is solar radiation most intense?
Solar radiation is most intense at noon.
What is a dynamic encounter?
A dynamic encounter is a situation in a game or narrative that adapts and changes based on the actions of the player or characters involved. It is designed to provide a more personalized and engaging experience by responding to choices and decisions made during the gameplay.
What types of radiation should you be worried about?
The most dangerous type of radiation is Nuclear radiation which is the one that should be most worried about.
What solar radiation is the most powerful?
Ultraviolet radiation
What type of radiation is the most harmful?
Gamma radiation.
Which radiation is the most easily absorbed?
alpha radiation :)
What is the origin of the word 'laser'?
The word is from 1960, an acronym of Light Amplification by Stimulated Emission of Radiation
Which radiation is most common on earth?
Solar radiation is the most common type of radiation on earth. The earth also emits thermal radiation from its crust as a result of decaying of uranium.
