If you are a foot from plutonium (a very radioactive element) for about 1 hour straight, you will develop something called radioactivity poisoning. It is a very painful disease that is able to kill you within a week.
No. Volcanic ash is harmful to inhale and can be toxic, but it is not radioactive.
Radioactive particles include alpha beta and positron they are not so harmful for human body the actually harmful are gamma radiations associated with these particles.
Americium is harmful to humans because is very radioactive.
Because it is radioactive
Francium is a radioactive element.
Yes
Einsteinium is extremely radioactive and dangerous.
It is not, radon is very harmful because it is radioactive.
just some
As a radioactive element, yes.
Rutherfordium is a synthetic element and its properties are not well-studied. However, it is expected to be highly radioactive and potentially harmful due to its radioactive decay. As with other radioactive elements, proper safety measures and handling protocols should be followed to minimize the risk of exposure.
Yes, because they are very radioactive and toxic.
