list the three products of
radioactive decay from the most penetrating to the least penetrating.
they are
1. gamma ray
2. beta articles
3. and
gamma ray
has no charge nor mass and it is not
particle s but electromagnetic radiations, so it is not affected by the
ionizing effects of air molecules or collision with air constituents, this is
why it can travel largest distance coupled with the fact that it has the
highest energy and speed.
beta
particle is having a charge as well as mass of a single electron, it can be
affected by the ionizing effects of air constituent like nitrogen molecules,
oxygen , water vapor etc. it move with the a speed ranging from 0 to 0.9995C,
where C is the speed of light and also has higher energy than alpha particles. this factors make it to be more penetrating
than alpha particle , though gamma rays are the most penetrating
alpha
particles is a helium nuclei, most massive and having a charge with of +2e, the
large mass will cause much “friction” while the large charge ( compared to beta
and gamma )will induce ionizing with objects, this affects it affect to
penetrate object and hence why it is immediately stop when it enters the
objects. so alpha is the least
penetrating.
