Alpha beta gamma.....COOKIES?
can anyone explain to me the effects of alpha, beta particles and gamma ray radiation to our body? regarding their penertrating power and ionizing capacity.
SAID:
A. alpha: very little pentrating power and are able to ionize a large number of atoms within the small area they were able to penetrate.
B. beta: they can penetrate paper or several millimeters of skin and about 1-metre of air. they are absorbed by aluminum or Perspex, a few millimeters thick. their ionizing capacity is less than that of alpha-radiation.
C. gamma: it has no electric charge and has great enetrating power. not even a thicj\k piece of lead or concrete will stop all of them, although, their ionizing capacity is smaller that that of beta-rays.
ASSUME THEY WERE RADIOACTIVE COOKIES CONTAING EACH OF THEM:if you were allowed to eat one, hold one and place one in your pocket, which cookie should be placed where so that you wil receive the least radiation?A B OR C?
EXPLAIN...
