Hello! These might be silly questions to the experienced, but this will be my first time trying gamma spectroscopy, so I'm a newbie. Firstly, I'm wondering if there's some software that will record changes in the spectrum over time? I know some people have been doing audio recording, but it doesn't seem like software is designed to analyze or export changing spectra? Basically I'd like to turn it on and start recording, then walk away for an hour and observe changes in emissions during that time. Secondly, how high can I trust calibrations? For example, if I calibrate with cobalt-60's 1.33 MeV, can I trust accuracy up to 20 - 40 MeV? Thanks for your expertise!
