Paper or foil absorbs beta ratation. The thicker it is the less radiation passes through. A detector senses how much radiation passes through and changes the production setting.
when you heat up or cool down radioactive substances, nothing changes how much radiation it emits.
In physics, radiation is a process in which energetic particles or energy or waves travel through a medium or space. There are two distinct types of radiation; ionizing and non-ionizing. The word radiation is commonly used in reference to ionizing radiation only (i.e., having sufficient energy to ionize an atom), but it may also refer to non-ionizing radiation (e.g., radio waves, heat orvisible light). The energy radiates (i.e., travels outward in straight lines in all directions) from its source. This geometry naturally leads to a system of measurements and physical units that are equally applicable to all types of radiation. Both ionizing and non-ionizing radiation can be harmful to organisms and can result in changes to the natural environment.
No. Dangerous radiation is produced by radioactivity, but equally dangerous radiation can also be produced by other means such as an X-ray machine. Radioactivity is the name we give to the processes where an unstable nucleus of an atom changes into a different nucleus. Particles such as alpha, beta and gamma are given off during the change; we refer to these particles as nuclear radiation. Radiation is technically any form of energy that can travel through space in the form of waves. So, light and microwaves and radio/TV broadcasting are all technically forms of radiation, and are not produced by radioactivity.
Light is emitted when an electron jumps from a higher energy orbit to a lower energy one. The wavelength (=colour) depends on the energy difference. Bigger is bluer, smaller redder.
All ionizing radiation in high doses causes irreversible changes to the skin...In some cases the change is caused by death. Say, for instance, that you were exposed to Alpha radiation, it would not penetrate deeply enough to pass through the dead skin cells. If you ingest an Alpha emitter, it could have lethal effects. Beta is perhaps the most dangerous. It penetrates deeply and causes damage to the DNA that can be expected to lead to skin and other cancers. On the other hand, Beta radiation is used to destroy tumors. Gamma radiation, same as X-rays, causes damage that, like Beta, is not limited to the skin. It has been said that there is no safe dose of radiation.
The amount of radiation changes across the spectrum.
Photoelectric effect changes electromagnetic radiation into electricity. Solar batteries utilizes this principle.

Seasons :)
solar radiation and thermal energy
If they are not shielded from the damaging radiation of the sun the solar rays can penetrate the layers of the space station.
Due to unstable atomic structures (or a weak nuclear force), radioactive materials release alpha particles as radiation.
because it is radiation and radiation can not be affected by temperature and/or concentration.
The nuclear waste gives off radiation. That radiation in large enough doses changes DNA in cells. When the DNA changes sometimes the cells can become cancerous. In even higher doses the cells will die.
