X-Rays

You've probably had an X-ray assessment of some part of your body. Health care professionals use them to look for busted bones, problems in your lungs and abdomen, cavities in your teeth and many additional problems. For example, mammograms use X-rays to look for tumors or doubtful areas in the breasts.

X-ray technology uses electromagnetic energy to make images. The image is record on a film, called a radiograph. The parts of your body emerge light or dark due to the different rates that your tissues absorb the X-rays. Calcium in bones absorbs X-rays the most, so bones look white on the radiograph. Fat and other soft tissues take up less, and look gray. Air absorbs least, so lungs appear black.

X-ray examination is painless, fast and simple. The amount of radiation exposure you receive through an X-ray examination is little.

Radiation Therapy

Radiation is a form of energy free in particles or waves. In high doses, radiation destroy cells or keeps them from multiply.

Radiation therapy is a cancer action. Its goal is to kill cancer cells and shrink tumor. Unlike cancer cells, most of your normal cells recover from emission therapy. Doctors try to protect normal cells by warning the radiation dosage and spreading treatment out over time. When they use radiation equipment, they shield as much of your body as probable while targeting the cancer.

The radiation for cancer action comes externally, from special machines, or internally, from radioactive substance that a doctor places in your body. Sometimes emission is used with other treatment, like surgery or chemotherapy.

Radiation Exposure

Radiation is energy that movements in the form of waves or high-speed particle. It occurs naturally in sunlight and sound effect. Man-made radiation is used in X-rays, nuclear weapons, nuclear power plants and cancer conduct.

If you are exposed to small amount of radiation over a long time, it raises your risk of cancer. It can also cause mutation in your genes, which you could pass on to any children you have after the contact. A lot of radiation over a short period, such as from a radiation emergency, can cause burns or radiation illness. Symptoms of release sickness include nausea, weakness, hair loss, skin burns and reduced organ purpose. If the exposure is large enough, it can cause untimely aging or even death. You may be able to take medicine to decrease the radioactive material in your body.

Radiation Emergencies

Radiation is a type of power. People are showing to small amounts of radiation every day from source such as sunlight. A radiation disaster would involve larger amount of radiation and could be caused by

* Dirty bombs - a mix of explosive with radioactive residue
* Fallout from a nuclear bomb
* Accidental liberate from a nuclear reactor or a nuclear weapons plant

A lot of emission over a short period can cause burns or energy sickness. If the exposure is large enough, it can cause untimely aging or even death.

Although there is no assurance of safety during a radiation tragedy, you can take events to protect yourself. You should have an adversity plan. Being ready can help reduce fear, anxiety and dead.
