What do scientist mean by radiation?
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.
Is radioactive energy the same as nuclear energy?
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.
What Will Absorb Beta Radiation?
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.
What happens to the amount of radiation a radioactive substance emits when you heat it up or cool it down?
when you heat up or cool down radioactive substances, nothing changes how much radiation it emits.
What part of the atom does nuclear radiation come from?
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.
What form of ionizing radiation in high doses causes delayed irreversible changes of the skin?
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.

How can working with X-rays cause cancer?
Radiation is the emission (sending out) of energy from any source. The light that comes from the sun is a source of radiation, as is the heat that is constantly coming off our bodies. When talking about radiation, however, most people think of specific kinds of radiation such as that produced by radioactive materials or nuclear reactions. Most forms of radiation have not been linked to cancer. Only high frequency radiation (ionizing radiation and ultraviolet radiation) has been proven to cause genetic damage, which can lead to cancer. One type of molecule that is sensitive to ionizing radiation is DNA, the part of the cell that contains the genes (blueprints) for each person's characteristics. Ionizing radiation can lead to a mutation (change) in a cell's DNA, which could contribute to cancer, or to the death of the cell. All cells in the body can be damaged by ionizing radiation. The amount of damage is related to the dose of radiation received by the cell. While the process of cellular change from radiation takes only a fraction of a second, other changes such as the beginning of cancer may take years to develop.
What is the differences between Radiation injury and Chemical injury?
Radiation injury, tissue damage or changes caused by exposure to ionizing radiation-namely, gamma rays, X-rays, and such high-energy particles as neutrons, electrons, and positrons.A chemical injury occurs where someone is exposed to a hazardous substance, either in the atmosphere or through direct contact with the skin.
What about radiation make it able to cause cancer and able to cure it?
Ionizing radiation can break chemical bonds.If the bonds broken are in nucleic DNA then genes may be corrupted, disabled, or enabled. These changes can sometimes turn a cell cancerous or more commonly kill it. Cancer cells reproduce much more rapidly than ordinary cells in the body. Cells that are reproducing actively are much more likely to die from a given ionizing radiation dose than quiescent cells. Thus an established growing cancer is often killed by ionizing radiation, curing it. The immune system usually still has to clean up afterwards, killing the last of the cancer cells for a complete cure.
How does radiation change across the electromagnetic spectrum?
The amount of radiation changes across the spectrum.
What system changes electromagnetic radiation into electricity?
Photoelectric effect changes electromagnetic radiation into electricity. Solar batteries utilizes this principle.
Do airplanes give off radiation?
No. Airplanes, by themselves, emit no more radiation than ore objects. When you fly you are exposed to additional radiation due to your altitude. This radiation is "ionizing" because it changes the structure of the atoms in your body. The radiation you receive flying is because you are higher above the ground and, therefore, have less air between you and space. Space bathes the Earth with radiation all of the time and air can stop some of it, as can any other object radiation passes through, such as your poor body. Air travel does not pose a health risk for anyone, normally. If you are an astronaut or a pregnant flight attendant, you might want to ask a doctor first. Otherwise, you will be quite safe.

What is an environmental factor that could cause a base sequence in DNA to be changed to a different base sequence?
Long term exposure to harmful genotoxic chemicals or ionizing radiation can cause changes in the base sequence of DNA
