A safety officer compares radiation sources used in a research facility. The sources have the same intensity and exposure time, and the same type of tissue is exposed in each case.
| Radiation source | Frequency / Hz |
|---|---|
| ultraviolet | 8.0 × 1014 |
| X-rays | 3.0 × 1018 |
| gamma rays | 6.0 × 1019 |
Compare the potential danger to tissue from the three sources. Explain your answer.
