What is 1 + 3?
They are able to detect the type of radiation
Particulate radiations travel a shorter distance through matter than electromagnetic radiation because?
Particulate radiations have mass
What can you say about Gegier Muller counter?
They operate with a voltage higher than a dose calibrator, They are used to measure small amount of radioactivity, They use halogen gasses as the quenching gas.
A dose calibrator requires specific tests to be done periodically to make sure it's working properly. (Daily)
Geometric dependence of a dose calibrator must be checked when?
Decay by electron capture (EC) is an alternative to?
Positron decay (Beta-Plus)
Decay by internal conversion (IC) is an alternative to the ?
Gamma- ray decay
The physical half-life of a radionuclide is the time it takes:
for the nuclide to decay to one half of the original activity.
Radioactive half life is the time?
required for radioactivity to reach one half of its original value.
A positively charged particle made up of two protons and two neutrons and released by a radioactive nucleus is called?
An electron released by a radioactive nucleus that causes a neutron to change into a proton is called?
The amount of time for half the atoms in a radioactive sample to decay is called?

High-energy electromagnetic radiation released by a radioactive nucleus are called
Aneutron in the nucleus decays into a proton, an electron, and an anti-neutrino is called a ?
