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 potential ...
