Six original Cambridge-style questions on the three radiations: what they are, their charges, their ionising and penetrating order, and identifying them from absorber experiments.
State the nature of alpha, beta and gamma radiation.
State the charge on each of the three types of radiation.
State what material is needed to stop, or greatly reduce, each type of radiation.
A source is unaffected by paper but is completely stopped by 3 mm of aluminium. Identify the radiation and give your reason.
Put the three radiations in order of ionising power, and in order of penetrating power. State the link between the two.
Explain why alpha radiation is fairly harmless outside the body but very dangerous if a source is breathed in.
Mark this once you have attempted all six and checked your working. It records a Practiced badge on the topic and adds a one-time bonus. Revealing the solutions alone does not count.
