why?
4. Which of the radioactive radiations has least penetrating power?
5. Mention one adverse effect of over exposure to radioactive radiations.

3) gamma Ray's are unaffected by electric and magnetic field. this shows gamma Ray's are uncharged as they do not experience a force when passing through the lines of a magnetic field.

4) Alpha

5) There is always risk of damage to cells or tissue from being exposed to any amount of ionizing radiation. Over time exposure to radiation may cause Cancer and other health problems.
