Radiation poisoning

We can classify radiation into ionizing and non-ionizing radiation, according to the effects it produces on matter. Ionizing radiation includes cosmic rays, X rays and the radiation from radioactive materials. Non-ionizing radiation includes ultraviolet light, radiant heat, radio waves and microwaves. In medical practice ultrasound and magnetic resonance imaging (MRI) involve non-ionizing radiation. +light n heat radiation produced by the sun *ionizing radiation is produced by some minerals in the earth *our bodies contain radioactive material *dose rate increases with altitude and latitude *natural rays- cosmic rays,gamma raysfrom the Earth, radon decay products in the air, and various radionuclides found naturally in food and drink.

*X rays, fallout from the testing of nuclear weapons in the atmosphere, discharges of radioactive waste from the nuclear industry, industrial gamma rays, and miscellaneous items such as consumer products *COMMON USES OF RADIATION IN INDUSTRY — Radiography of welds and joints.

Security inspection of bags and parcels. Level gauging of container contents.*environmental radiation- nuclear weapon tests, radioactive discharges,depleted uranium, *contaminated areas *Laptops,CordlessPhones,refrigerators, Wireless Routers(Wi-Fi) ,Cell Phones , The likelihood of such effects depends on the amount of radiation that a person receives, whether from a natural or an artificial source. As the effects of ionizing radiation have become better understood during recent decades, a system of radiological protection has been developed to protect people from exposure to sources of radiation.

3) The unit used to measure radiation dosage is the rem, which stands for roentgen equivalent in man. It represents the amount of radiation needed to produce a particular amount of damage to living tissue. Although a dose of just 25 rems causes some detectable changes in blood, doses to near 100 rems usually have no immediate harmful effects. Doses above 100 rems cause the first signs of radiation sickness including: nausea vomiting headache some loss of white blood cells.

Doses of 300 rems or more cause temporary hair loss, but also more significant internal harm, including damage to nerve cells and the cells that line the digestive tract. Severe loss of white blood cells, which are the body’s main defense against infection, makes radiation victims highly vulnerable to disease. Radiation also reduces production of blood platelets, which aid blood clotting, so victims of radiation sickness are also vulnerable to hemorrhaging. Half of all people exposed to 450 rems die, and doses of 800 rems or more are always fatal.

Besides the symptoms mentioned above, these people also suffer from fever and diarrhea. As of yet, there is no effective treatment–so death occurs within two to fourteen days. In time, for survivors, diseases such as leukemia (cancer of the blood), lung cancer, thyroid cancer, breast cancer, and cancers of other organs can appear due to the radiation received. 4)Wear a wired headset for cell phones, or talk on a land line or speaker phone as much as possible in order to keep your cell phone away from your head. Use wired Ethernet instead of Wi Fi. Sit as far as possible from your television screen.

Use a desktop computer rather than a laptop, and sit back from the monitor. If you have a laptop (as I do), don’t place it directly on your lap. Utilize natural lighting as much as possible, and only turn on as many lights as you need. Radiation is scary stuff in terms of health consequences; however, that doesn’t mean you need to run around in a panic or try to live in a bubble. Take charge of your health by minimizing your exposure to radiation with these tips, and by protecting yourself via your diet, and you’ll be able to worry much less about radiation.

Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells. X-rays, gamma rays, and charged particles are types of radiation used for cancer treatment. The radiation may be delivered by a machine outside the body called a linear …

Gamma rays are used in medicine, the nuclear power industry, the military, scientific research, industry, and various consumer products. Gamma radiation is also important in the medical sciences. Ionizing radiation is more harmful to cells when they are dividing (replicating …

Injury to living tissue results from the transfer of energy to atoms and molecules in the cellular structure. Ionizing radiation causes atoms and molecules to become ionized or excited. These excitations and ionizations can: * Produce free radicals. * Break …

In January 2012, the Center for Disease Control and Prevention released their Preliminary Data for the Leading Causes of Death in the United States. Their report showed that cancer is ranked at number two once again. As cancer rates remain …
