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...

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?
What is radioactivity in nuclear chemistry? What happens to a radioactive isotope as it decays? Does the number of neutrons change in alpha decay? For an atomic element that undergoes decay, how do we know that for every half-life period half of the element will decay?
Atoms: All of the elements that we know to exist are listed on the periodic table. If you notice, the atomic masses of each element are different, and they are generally decimal values. This value is the weighted average of each isotope for that element. ...
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...
