What types of injury of public health concern are associated with exposure to each of the different forms of radiation? How does the risk of each injury vary with the dose of the radiation in question?
Below is a Sample Solution.
Remember! This is just a sample. You can get a custom paper from one of our expert writers.
1. Xray radiation
Prolonged exposure to x ray radiation can cause severe cell necrosis around the area exposed to radiation. Gametes exposed to Xray radiation can undergo spontaneous mutations. Low doses have mild effect on cells.
2.Gamma radiation
High doses of gamma radiation cause cell death and severe skin damage. Gamma radiation carries high energy ions that can cause cell injury and tissue death. Low doses can still cause necrosis and tissue injury.
3. Beta radiation
Unlike gamma radiation, beta radiation carries low energy ionisation particles that can cause mutations following prolonged exposure. Low doses have mild effects at a cellular level.
4. ultraviolet radiation
Prolonged exposure to high doses of ultraviolet radiation can cause cataracts and skin cancer. Low doses have mild effects on skin and eyes.
