Respuesta :
Place a piece of paper in front of and behind the monitor. If the numbers are reduced sufficiently, the source emits alpha particles.
What is radioactivity?
The act of producing radiation spontaneously is known as radioactivity. This is accomplished by an unstable atomic nucleus that wants to give up some energy in order to move to a more stable form.
Determine the background count rate first, followed by the source count rate without an absorber, to identify the radiation type.
Put a piece of paper in front of the monitor and behind the source. The source emits alpha particles if the numbers are sufficiently decreased.
Hence by founding the count rate the teacher will find the type of radiation.
