Fresh, or rather bottled, water, is also (44) babies have been drinking as far away as Tokyo, after the levels of radioactive iodine 131 in the water there proved too (45) . (One preventative move is taking potassium iodide, commonly added to table salt here. ) This afternoon, there ...
The radioactive isotope of potassium occurs at an extremely low concentration, and potassium is necessary for good health [source: HPS]. X-rays are essentially the same as gamma rays, but their origin is different. Where gamma rays come from inside the nucleus of an atom, X-rays come from...
In order to answer the question “how much radiation is too much radiation?”, we must first define what exactly we mean by “radiation.” In physics, the term “radiation” typically refers toelectromagnetic radiation –that is, forms of energy which propagate by means...
To make sure furosemide is safe for you, tell your doctor if you have ever had: an electrolyte imbalance (such as low levels of potassium or magnesium in your blood); enlarged prostate, bladder obstruction, or other urination problems; ...
Even though gallium is much more expensive than silicon, it's become a popular semiconductor material in the latest generations of smartphones. Smartphones communicate with cellular data networks using radio frequency (RF) chips, and RF chips made with gallium arsenide give off less heat than sili...
What is radioactive dating? The half-life of carbon-14 is 5730 years. Carbon-14 can be used to date objects that are a maximum of about 58,000 years old. Approximately how many half-lives is this? How much carbon-14 is present i ...
How are potassium and argon related to radiometric dating? How was carbon-14 discovered? How is radioactive decay used in absolute dating? How does absolute dating determine the age of the Earth? Who discovered radiocarbon dating? How does radioactive dating work?
Eating a banana, for example, is 0.01 millirem of exposure. The average person receives about 30 mrem of dose from the decay of potassium-40 in their own bodies every year. The maximum external dose received by members of the public after the Three Mile Island accident was about 100 mrem...
Water- Fifteen gallons of drinking water is recommended to last people inside the shelter as long as possible. It may be necessary to stay inside a fallout shelter for as much as two weeks after a nuclear attack, so sufficient amounts of water will guarantee survival. ...
However, the rate of fluid resorption continually changes over time with changes in environmental conditions, that is, with darkness and light, with the partial pressure of carbon dioxide, with local extracellular potassium ion concentration, with pH and with extracellular and intracellular concentrations...
