Radiation doses and damage.

The damage caused by radiation depends on the radiation dose.

Radiation dose depends on the tyoe and amount of radiation you've been exposed to.

The higher the radiation dose, the more at risk you are of develping cancer.

Radiation dose depends on location and occupation.

Certain underground rocks like granite can cause higher amounts of radiation, especially if they release radioactive radon gas.

Nuclear industry workers and uranium miners are typically exposed to 10 times the normal amount of radiation. They wear protective clothing and face masks to stop them from touching and inhaling the radioactive material. 

Radiogrpahers work in hospitals using ionising radiation and so have a higher risk of radiation exposure. They were lead aprons and stand behind lead screens to protect them.

At high altitudes the background radiation increases because of more exposure to cosmic rays. Pilots have an increased risk of getting some types of cancer due to this.

Alpha and beta- deflected by electric and magnetic

Alpha particles have a positive charge and beta particles have a negative charge.

When travelling though a magnetic or electric field, both alpha and beta particles will be deflected.

They're deflected in opposite directions because of their opposite charges. 

Alpha particles have a larger charge than beta particles and feel a greater force in magnetic and electric fields. However, they are deflected less because they have a greater mass. 

Gamma radiation is an electromagnetic wave and has no charge. This means it doesn't get deflected by electric or magnetic fields.
