Sources of radiation include natural phenomena like cosmic rays and radioactive elements, as well as human-produced sources such as X-ray machines and nuclear power plants. Say the word "radiation" to three different people, and you'll probably get three different reactions. Your aunt may tell...
Radiation 101: how far will radioactive water leaking from nuclear plant go?(USA)Radiation is contaminating seawater near the Fukushima Daiichinuclear complex, but workers are...Grier, Peter
Radiation vs. Radioactive X-Rays It is natural that we might confuse X-rays with radiation from radioactivity. You may think that man-made radiation is more dangerous than an equal amount of natural radiation, but this is not necessarily the case. Most background radiation comes from radioactiv...
RADIATION IN FOOD & WATER A source of concern for many people is the prospect of radioactive contamination of their food or water. This can occur from radioactive contaminants being ingested by animals that are then used for food, such as Strontium-90 found in cow’s milk after Chernobyl, ...

However, even then they don't typically cause radiation sickness — instead, they lead to lung cancer. Beta particles are electrons that move very quickly — that is, with a lot of energy. Beta particles travel several feet when emitted from a radioactive source, but they're blocked by ...
It consists of two plates with a voltage across them, along with a radioactive source of ionizing radiation, like this: The alpha particles generated by the americium have the following property: They ionize the oxygen and nitrogen atoms of the air in the chamber. To "ionize" means to "...
In another type of radiation therapy termed low dose rate brachytherapy, radioactive pellets about the size of a grain of rice are inserted into the prostate. High Dose Rate Brachytherapy High dose rate brachytherapy applies more radioactive sources temporarily into the cancerous prostate gland. ...
Is it safe to drink radioactive water? Different doses of radiation cause different health effects. Drinking water that has radionuclides in it puts you in contact withvery low doses of radiation every day. You have a higher risk of getting cancer if you drink water with radionuclides in it...
How many grams of cobalt are remaining after 15 years? What is the formula for radioactive decay? Carbon-14 has a half-life of 5,730 years. In a plant fossil, you find that the 14C has decayed to 1/16.0 of the original amount. How...
