· Can cause things to
heat up. The heating
effect of absorbed
radiation can damage
living cells

Ionisation
Some types of radiation are dangerous because
they "ionises" atoms ­ in other words, it turns
them into ions by "knocking off" electrons:
Ionisation causes cells in living tissue to mutate,
usually causing cancer. High doses can destroy…read more
