The correct answer is the last option. Alpha particles are generally considered more safe than those that emit beta particles since they can be blocked very easily. They are least dangerous since they do not penetrate deeply in the skin. Clothing can even stop the penetration of alpha particles. However, they can be very dangerous when ingested or inhaled.

Answer from: Quest

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
