- Ionsing Radiation
- Radioactive substances give out radiation all of the time.
- There are three types of nuclear radiation
- Alpha Particels
- Alpha is the least penetrating
- all three are ionising radiation: they can knock electrons out of atoms and form charged particles..
- Beta Paricels
- all three are ionising radiation: they can knock electrons out of atoms and form charged particles..
- Alpha is the least penetrating
- Beta Paricels
- Gamma Rays
- gamma is the most penetrating.

- Radiation can be harmful, but it can also be useful - the uses of radiation include to:
- detect smoke
- gauge the thickness of paper
- treat canser
- sterilizer medical equipment.
- Nuclear radiation
- comes from the nuclus of an atom
- Substances that give out radiation are said to be radioactive..
- All radiation transfers energy
- All types of radiation become less intense the further the distance from the radioactive material, as the particles or rays become more spread out..
- The thicker the substance, the more radiation is absorbed.
