How Radiation Works using Americium 241, Alpha Particles and Gamma Rays

# data[].attributes.attachment_link.description
How radiation work using Americium 241 as an example as it radiates alpha particles and gamma rays, slowly undergoing radioactive decay to become Neptunium 237. Full animated explanations are given. Also there are live demonstrations using an Americium 241 pellet from an ionizing smoke detector and a spark gap powered by a homemade high voltage power supply.
