PRACTICAL: Investigating the penetration of radiation

QuestionAnswer
What device is used to measure radation? A Geiger-Müller tube
What radiation must we measure a few times before the experiment and then subtract off all our results? Background radiation
How do we find counts per second of radiation? Counts/time period
If the count rate remains the same when a material is inserted, what does it mean? The radiation can penetrate that material
What will happen to the count rate if the radiation is completely absorbed by the material? It will drop to 0
What safety precautions should be taken in regards to storing the radioactive sources? They should be kept in a lead-lined box
How must we handle radioactive sources? Only with long tongs
What must be kept the same in this experiment? The location of the experiment, to avoid changing background radiation
