Description
SP4-1921
his instrument simulates a Geiger Counter but without using
actual radioactive sources. It is therefore completely safe.
Powered by 240/12V.AC. Plug Pak, this microprocessor
based instrument can display the counts of particles leaving
an imaginary r/a ‘source’ and also can display the number
of r/a particles remaining inside the ‘source’. The concept
of half-life is easily demonstrated and the random nature of
the particle counts can be shown. The unit is used also in
Maths in the study of ‘random numbers’ and statistics.
