Penetration of Ionising Radiation
Investigating absorption of alpha, beta and gamma
Investigate how distance and barriers affect the penetration of ionising radiation using a virtual GM tube and counter.
Interactive simulations to help you master physics concepts
"Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less."
Investigate how distance and barriers affect the penetration of ionising radiation using a virtual GM tube and counter.
Roll a tray of dice, remove the ones showing the dark face, and plot the decay curve — a hands-on model of the random nature of radioactive decay.
Visualise the fission of uranium-235 by neutron bombardment. Explore chain reactions and understand how nuclear reactors control the process.
Explore how hydrogen nuclei fuse to form helium, releasing enormous energy. Understand the conditions required for fusion and why it powers the Sun.
