What are Geiger counters? How do they work? Let's take a closer look!Artwork: The basic concept of a Geiger counter—a tube, attached to a meter, that can detect and measure particles of radiation.Sponsored linksContents What is radioactivity? Ionizing radiation What is a Geiger counter?
See How Radioactivity Works for complete details. Nuclear medicine imaging is useful for detecting: tumors aneurysms (weak spots in blood vessel walls) irregular or inadequate blood flow to various tissues blood cell disorders and inadequate functioning of organs, such as thyroid and pulmonary function...
As we have seen, radioactivity is "natural," and we all contain things like radioactive carbon-14. There are also a number of man-made nuclear elements in the environment that are harmful. Nuclear radiation has powerful benefits — nuclear power generates electricity while nuclear medicine detects...

Once inhaled or ingested, depleted-uranium smoke can do a great deal of damage to the human body because of its radioactivity. See How Nuclear Radiation Works for details. The Pentagon has developed tactical nuclear weapons to reach the most heavily fortified and deeply buried bunkers. The idea...
Why does it seem so hard to achieve? Too many people are intimidated by placing a full turkey on the grill. You don't have to be. Some chefs worry about the too-dry turkey leg. Here's some advice on avoiding the pitfalls and getting the best out of any bird. Bone-in Turkey ...
In dermal application studies of 14C-labeled-lanoconazole cream on rats, 83% of the total radioactivity was recoverable from the stratum corneum after 24 hours. The radioactivity remained detectable for up to 96 hours, which is significantly longer than clotrimazole and bifonazole. In humans, lan...
Solution: Because carbon-14 decays due to radioactivity, we can use the exponential decay equation. N(t) = A e(-kt). From Problem 1, the decay constant for carbon-14 is 1.21 * 10(-4) /years. Additionally, if the original population of carbon-14 is A, then N(t) = 0.65A. 0.65...
