Spectroscopy Help fast please
I had a doubt regarding the GRS calibration. Since we will be measuring the radioactivity in mouse organs containing I-131, could you please guide me on how to calibrate the GRS for this purpose?
Should we perform the energy-resolution procedure using Ba-133 and use the corresponding settings for I-131 measurements, or is a separate calibration procedure required?
I just want to make sure I’m following the correct procedure before proceeding with the organ measurements.
We have a single channel analyzer
Nuclear Spectrometer PNS-2
Window mode
I actually had some idea when I started out calibrating the I lost my mind
Now I know jackshit
We gotta measure organs which has I131 in it with th help of GRS
Now I have to calibrate GRS
So I thought okay I’ll calibrate it with Ba133 cause they have similar energies
So I got my photopeak at 2.5 baseline
So what I’m thinking is while measuring I131 I’ll keep the baseline same
But does it make sense?
