Question 46

In an experimental setup, a radioactive source is directed towards a radiation detector. With a thin sheet of paper placed between the source and the detector, the detector continues to show a reading significantly higher than the background level. When the paper is replaced by a 5 mm thick aluminium sheet, the reading on the detector falls to the background level. Which type of radiation is being emitted by the source?

A

α\alphaα-radiation

B

β\betaβ-radiation

C

γ\gammaγ-radiation

D

X-ray\text{X-ray}X-ray radiation
