HideShow resource information
Alpha, beta and gamma radiation can enter...
living cells and collide with the molecules

These collisions cause...
ionisation, which can destroy the molecules
2 of 11
Lower doses cause minor damage...
without killing the cell
3 of 11
This can make mutant cells...
divide uncontrollably (cancer)
4 of 11
People can get radiation sickness if...

5 of 11
BETA AND GAMMA are dangerous...
