Worker P receives a dose of 40 mSv of gamma rays. Worker Q receives a dose of 40 mSv of a different type of radiation. A scientist says that the risk of harm to the two workers may not be the same. Why might the scientist be correct?
The risk depends on the distance travelled by the radiation.
The risk depends on the time taken to measure the dose received.
The risk depends on the wavelength of the light given out by the source.
The risk depends on the type of radiation as well as the size of the dose.
