Teaching and learning about ionising radiation takes us into one of those physics contexts where the phenomenon being studied...

Teaching Guidance 14-16

The following questions were given to 144 school students aged 15–16 years and drawn from four schools. The students had all...

Teaching Guidance 14-16

It is quite common for students to use the three terms radioactivity , radioactive material and radiation interchangeably.

Teaching Guidance 14-16

This teaching and learning challenge is related to the previous one. If students are not clear about the difference between...

Teaching Guidance 14-16

The idea of irradiated objects necessarily becoming radioactive is quite common in everyday thinking but is not correct. Many...

Teaching Guidance 14-16

It is quite common for teachers and students to talk about alpha, beta and gamma radiation. In fact, on first discovery...

Teaching Guidance 14-16

Some students attribute the property of being radioactive to alpha or beta particles.

Teaching Guidance 14-16

When observing demonstrations with radioactive sources and a Geiger–Müller tube, students are likely to associate a high rate...

Teaching Guidance 14-16

Students often assume that gamma radiation is more dangerous than alpha and beta because it has a greater penetrating power.

Teaching Guidance 14-16

It is quite common to see statements along the lines of alpha particles are more ionising than beta , but this is not actually...
