The Gilbert U-238 Atomic Energy Laboratory is credited as being the most dangerous toy ever created. Keep reading to learn ...

It includes an electroscope to measure radiation levels, a spinthariscope that allows radioactive decay to be seen on a fluorescent screen and a cloud chamber that enables the user to watch alpha ...

How to make a particle detector cloud chamber at home If your aim is to detect any old particles that happen to be passing ...

The cloud chamber detects secondary cosmic rays and radioactive decays by making alcohol clouds along the particle paths through the chamber. Particles ionize alcohol molecules as they pass through ...

The laboratory kit contains a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second, a spinthariscope showing the results of radioactive disintegration on ...

In 1911, Wilson became the first person to photograph the lines made by a particle moving through his cloud chamber. He was eventually awarded the Nobel Prize for the invention in 1927.

He describes the nature of alpha, beta and gamma radiation, and observes the traces of alpha particles in a cloud chamber. He also explains the concept of half-life and carbon dating. Teacher Notes ...

It also came with an electroscope for measuring radiation levels, a spinthariscope for visualizing radioactive decay on a screen, and a cloud chamber that offers the viewer evidence of alpha ...

FOR various investigations, such as for large range radiation or when ionisation occurs infrequently, it is an advantage to use high pressure in a Wilson cloud chamber1. We have developed a Wilson ...
