Alpha decay

• Nuclease releases alpha particle (2 protons and 2 neutrons)

• Atomic mass decreases by 4 and atomic number decrease by 2

• Low penetration, deadly via injestion

• C^12 →Be^8

Beta decay

• Neutron converted to proton/vice versa. Release of electron (beta minus) or positron (beta positive)

• Mass number stays the same, atomic number decreases or increases by one to new element.

• Moderate penetration

Gamma decay

• Releases photons

• Very high penetration
