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.
