I'm doing high school physics and if a question says something like: A radioactive source gives count rate of 110 counts per second
Can you say that the ACTIVITY is also 110 bq? My second question is how would a gieger counter detect gamma radiation? It is the least ionising of all three radiation so not many particles inside the G-M tube would be ionised giving a low count rate? where as alpha particles would ionise a significant amount more particles then gamma radiation giving a higher count rate?
How would a geiger counter compensate for these different ionising powers?
