Hi there,
Can anybody explain to me the practical difference between having a geiger that can detect down beta down to 250keV versus one that detects down to 50keV?
Does it mean that because it is less sensitive it will look like you've had lower exposure? (ie the microseverts/hr will look lower?)
Or does it not work that way?
thanks heaps!!
Jo

Yes, if there is radiation that your geiger counter can't measure, you are probably clueless.
Different isotopes radiate with different energy. If you try to measure an isotope that radiates with 50keV but you only have a counter that can detect 250keV and above, you may only be able to detect some X-rays from bremsstrahlung. (I don't understand why there is no real English word for it...)
Of course the ySv will look lower. You have to choose the right tool for the job.
