Ionising and Detecting Radiation

Radioactive decay and ionising radiation become alpha particles and beta particles and gamma ray and ionising Radiation they knock out. And Atoms become charge.

Alter the structure

Alter the bonding

Changes its properties

And new structure and bonding and properties take chemical reactions where the previously couldn’t be chemical reactions.

And ionisation damage DNA and can lead to cancerous tumors.

Alpha particles have the highest ionising ability and they have low penetrating power.

Gamma rays has the lowest ionising ability and has the highest penetrating power.
