Q
What is the nature and ranges of Beta Radiation?
A
Typical range= 10s
Transmutation of neutron and proton = electron
Will be blocked by aluminium

Q
What is the nature and range of Alpha Radiation?
A
Relatively slow and heavy particles
Mass is approximately 4 protons
Low penetration and will be stopped by paper

A
Is emitted by an unstable nucleus
Wavelength is less then 10 power of -11
High energy and electromagnetic waves
Will be blocked by lead
