Hello Gamma Enthousiasts,
My name is Alfred Apperloo, I live in the Netherlands , Europe. Gamma spectrometry is one of my hobbies. My profession is kidney specialist (acute and chronic renal failure, kidney transplantation, nephrotic syndrome, ICU, hypertension etc.) In the past, I used 125 Iodine and 131 Iodine isotopes intravenously to accurately study renal perfusion and glomerular filtration rate in patients with renal diseases and healthy volunteers. I titrated their blood and urine samples myself to yield maximal accuracy.
This sparked my interest for radioactivity. A few years ago I crafted my first gamma spectrometry setup. I used my ThermoScientific Electra rate meter with a Bicron scintillator. I connected a simple capacitor to the HV output of the Electra with a T-piece and connected this signal to the PC soundcard with PRA running. Resolution and linearity were mediocre but I was agitated that it appeared possible to obtain a gamma spectrum with only very simple equipment. A few month later I was able to register far better spectra using a 2x2 inch NaI probe from Scionix combined with GammaSpectacular 1100A and an external USB soundcard adapter, E-MU 0204. Shortly thereafter I got the GG2012, a low budget portable MCA, with outstanding performance in combination with the Scionix probe.
