Radiation Experiment AIM: o To explore the properties of radiation o To examine how the intensity of the radiation measured depends on the distance from the source to the detector and on shielding placed between the source and the detector o To examine the differences between alpha beta and gamma radiation SAFETY PRECAUTIONS o Radioactive materials must be handled and stored safely o Use tongues to handle the radioactive materials o Don't point the radioactive material towards other people o The voltage used for GM tube is high. Therefore do not touch the back of the instrument o Wash your hands thoroughly after the experiment METHOD o Natural radiation exists around us. If we want to study radiation we first need to measure this "background radiation" that is always present and subtract its effects from our results. We will use the Geiger-Mueller detector to count the average background radiation. o Observing the effect of distance on intensity: Measure the distance from...
