Radioactivity is a subject that many teachers find daunting. We take a look at how to safely carry out effective experiments that teachers can replicate in the classroom. David Richardson from the Institute of Physics demonstrates to three teachers with different backgrounds how they can handle radioactive sources safely. He shows a variety of experiments using alpha, beta and gamma ionising radiation. Supporting animations help to explain what is happening on an atomic level. David also gives the teachers some suggestions of starter activities to grab the attention of the students and draw them into the subject. Additional safety points are covered by John Ellis from CLEAPSS, the school science support service.
