(Ionizing Radiation Exposure)
- Ionizing radiation—a high-frequency radiation that is able to damage cells, has also been linked to cancer and other health problems
- Nonionizing radiation—low in frequency and is not known to cause cancer (except for UV rays)
|Ionizing Radiation||Nonionizing Radiation|
|Gamma rays||Visible light|
|UV rays (high-energy)||Microwaves|
|Sub-atomic particles||Radio waves|
|UV rays (low-energy)|
- Radiation therapy used to treat certain types of cancer
- Radioactive elements in the soil or public works systems (eg, water supply)
- Workplace environment (eg, uranium mines)
- Radiation from nuclear disasters
