The radiation given off by a radioactive source can be measured with a. The weak radiation should be recorded in units ofbecause the lab sources are extremely low on thescale. Radiation is a random event so it is best to make each measurement.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
