Is radiation with more penetrating power more dangerous than one with the least?

Answer 1

alpha is the most dangerous but it has the lowest penetrating power ie. it can be stopped by your skin

beta is the next most dangerous and medium penetrating power ie. it can be stopped by a few sheets of paper

gamma is the leest dangerous but most penetrating ie. a large block of lead will be needed to block it

Answer 2

The higher penetrating radiation will tend to go right through you so it will tend to do less damage depending on how lucky you are an the DOSE you get . Some radiation gets trapped in the body and bounces around causing more damage than one that just goes on through....but it generally revolves around the amount of radiation you are exposed to.

Answer 3

it depends on how u define 'dangerous' being exposed to any radiation for different periods of time will kill you, but it depends on what kind of radiation, for how long, and several other factors. so the answer to your question is, it depends.

Answer 4

Normally, yes. You skin absorbs alpha particles, for example, preventing them from doing any damage (however, this is not true if you swallow something that is an alpha particle emitter).
