The inverse-square law for gamma rays

Level control

The stream of particles emitted from a radioactive source diminishes over time. A radioactive substance decays according to certain physical laws. In the special case of a radioactive substance comprising only one irradiating component, the quantity of material diminishes ...

Half-life and radioactive equilibrium

Principle

The half-life of a Ba-137 m daughter substance eluted (washed) out of a Cs-137 isotope generator is measured directly and is also determined from the increase in activity after elution.

Tasks

1. To measure the activity of the isotope generator as a function of time ...

Counter tube characteristics

The counter tube uses the ionising effect of high-energy radiation in order to measure the intensity of the radiation. The counter tube characteristics describe its working range, i.e. the voltage range in which it reliably counts the incoming particles.
