Hi there.
00:03
This question is about the three types of radioactivity.
00:07
Alpha, rays, beta, rays, and gamma.
00:15
All right, so alpha rays, these are, of these three, these are the least penetrating, and it's because these are essentially a helium nucleus, with an atomic number of two and a mass number of four.
00:29
So these are definitely particles.
00:33
Beta radiation is an electron, the negative charge, a mass number of zero, and actually atomic number, which is listed as a negative one.
00:53
And that's so that when this beta particle is put into nuclear equations, the numbers work out.
01:01
But since this is an electron, beta rays are also composed of particles, these electrons.
01:09
Gamma, however, gamma radiation.
01:13
This is simply radiation.
01:18
We find this on the electromagnetic spectrum.
01:20
It's very high energy...
