A nuclear isotope emits radiation which is detected by a Geiger-Müller tube held at a distance of about 10cm from the radioactive source. The radiation is stopped completely by a 2mm thick sheet of lead. What can be deduced from this information about the emission from the isotope? A It could be alpha and beta radiation, but not gamma radiation. B It could be alpha and gamma radiation, but not beta radiation. C It could be beta and gamma radiation, but not alpha radiation. D It could be alpha, beta and gamma radiation.

The answer is A Alpha because Although alpha particles cannot penetrate the skin, if it gets into the body it can ionise many atoms in a short distance. Beta because Beta particles are much more penetrating and can travel easily through skin. These particles are stopped by lead
