explain it...PLEASE? I am really confused!?

Question

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...

Answer 1

The less direct contact you would have the better of you are.

Eating would be worst of all. obviously the most contact and radiation would be all over your body.

Picking between the other two can be a problem.
Holding it would be bad for your hand...
but putting it in your pocket would bring radiation dangerously close to your reproductive organs that are very susceptible to radiation damage.

Technically in your pocket would be least dangerous but if I had to make a choice I would go for the hand as holding it would protect the rest of my body ( at least from alpha a beta) and because just a layer of clothing would hardly do any good and my whole body would be exposed to radiation.
