Radioactive substances can seriously damage health. Those that work with them must take care to reduce their effects. What methods can we use and how do they work?
- Exposure to radioactive substances can be both dangerous and beneficial to humans.
- Geiger counters are used to detect the number of radioactive particles encountered per minute.
- Photographic film badges are worn by nuclear power plant workers to measure radiation exposure.
- Protective clothing, machinery and shields reduce contact and increase the distance from radioactive material.
Exposure to radioactive substances can be dangerous to humans.
But radioactive substances have useful applications - for example, in medicine where they are used in the production of X-rays and in the treatment of cancerous cells.
Or in nuclear power stations, where they are used to generate electricity.
Because of the ...
