What is Nuclear Radiation? | Physics | the virtual school

If you were walking down the road and you
saw this can outside your house what would you think? Radiation is something that makes us feel
very, very uneasy, but what do we mean when we say radiation? Radiation comes from part of the atom called
the nucleus. The nucleus is made up of neutrons and protons
and it’s the centre of the atom. Usually this is stable but if it gives off
radiation we call this unstable. An unstable nucleus will give off pieces of
itself. If the atom gives off radiation we call it
radioactive and it can either give off radiation in the form of energy or in the form of a
particle. This type of atom we call radioactive and
the actual atoms are called radioisotopes. Most atoms are not radioisotopes because they
are completely stable.

    veryone knew something wonderful was going to happen that night, but few could have predicted the evening’s entertainment would ultimately change the world.

    The London crowd was sitting in a darkened room. Candles and oil lamps—the way people lit their homes (with fire) in the early 18th century—were doused. Francis Hauksbee (Hawksbee) was about to conduct an experiment.

    It was 1706, and this British scientist had produced an electrostatic generator. In a way, he was studying a type of lightbulb with an eye toward understanding electricity. Beginning his career as Isaac Newton’s lab assistant, Francis now held a respected position within the Royal Society.

    Since Newton had become the Society’s President, in 1703, he had staffed the scientific institute with people he could trust (and on whom he could rely) to help with weekly demonstrations.

    It was one of those fantastic demonstrations which Hauksbee was about to commence.

    0:43 "it can either give off radiation in the form of energy or in the form of a particle." – I think this is a bit inaccurate. It's not either/or, it's both. The particle (e.g. alpha) carries the energy. (I'm not an expert but that's my recollection).
