Radiation dose

Question 1

What affects your Radiation dose?

Answer 1

Type and amount of radiation you’ve been exposed to

this can be affected by location and occupation

Question 2

The [ ] the radiation does, the more at risk you are of developing [ ]

Answer 2

higher

cancer

Question 3

Certain underground (eg. [ ]) can cause higher levels at the surface, especially if they release radioactive [ ] gas, which tends to get [ ] in people’s house

Answer 3

granite
radon
trapped

Question 4

Nuclear Industry workers and uranium miners are typically exposed to 10 times the normal amount of radiation. What safety measures are put in place for them? (4)

Answer 4

Protective clothing and face masks - prevent inhaling / touching radioactive material
Special radiation badges
Regular check-ups

Question 5

Radiographers are at a higher risk because they use ionising radiation, what safety measures do they use?

Answer 5

Wear lead aprons and stand behind lead screens to protect them from prolonged exposure to radiation

Question 6

How does altitude affect background radiation?

Answer 6

At high altitude (eg in planes) the background radiation increases due to more exposure to cosmic rays. Commercial pilots therefore have a higher risk of cancer

Question 7

How does being underground affect radiation dose?

Answer 7

Increases due to all the rocks around, therefore miners are at risk
