Question

Which of the following statements is correct?

1) Alpha, beta, and gamma rays all give the same radiation dose.
2)Alpha radiation always causes more damage than X-rays.
3)Ultraviolet is as ionising as gamma rays and X-rays.
4)Long exposure to low-energy radiation could give the same dose as a short burst of high-energy radiation.

Answer 1

4) Long exposure to low-energy radiation could give the same dose as a short burst of high-energy radiation.

Step-by-step explanation:

When it comes to ionizing radiation, absorption should be kept as low as reasonably achievable (ALARA). This can be achieved by control of time spent in the vicinity of the source, the distance to the source and the use of personal protective equipment (PPE).

A short burst of high-energy radiation releases or generates a high radiation dose in a short time frame. This can also be achieved due to long exposure to low-energy radiation, which results into the gradual accumulation of the dose.
