Gamma Spectroscopy Kits

Gamma Spectroscopy Kits

Fun Discovering Nuclear Physics

Anyone with interest in learning or teaching physics must at one point have considered a gamma ray counting lab, but until now, the price tag for a complete spectroscopy set has made it almost impossible, therefore we present our range of affordable MCA Systems, perfect for science industry and education. Our systems come complete with gamma detector,  multichannel analyser, all cables, manual and a high impact foam lined carry case. Our after sales service guarantees that you will be doing gamma spectrometry quickly, and for a lot less money than you would expect, making your research grant stretch further.

Advantages of choosing separate spectrometer and detector.

While it may at first seem convenient to buy a spectrometer with built in detector, the avantages of having a separate spectrometer are many. Unfortunately there is no single gamma detector suitable for the entire range of energies that we might be interested in, so we end up having multiple detectors with different size and types of crystal scintillator. Fortunately most if not all your detectors with an SHV connector will be compatible with the spectrometer.

Detecting X-Rays

X-Ray detectors are designed to have good resolution in the low energy end of the spectrum and low efficiency at the high energy end of the spectrum. This is usually achieved by using a thin 2 mm slice of scintillation crystal covered by a thin Aluminum or Beryllium window. This construction will assure almost full absorption in the energy range 4 keV to 100 keV. whilst being almost blind to the higher energy gamma.

Detecting Higher energy gamma rays

The typical medium size 1.5" NaI(Tl) detector (38 x 38 mm), is a great all round detector, it is almost 100% efficient up to around 150 keV and drops to around 40% at 3000 keV

The popular 2" NaI(Tl) detector is around 100% efficient up to 200 keV and drops to 50% at 3000 keV. These 2" detectors are small enough to be considered portable and good for detecting the naturally occurring radioactive isiotopes (N.O.R.M.)

The next common size is the 3" NaI(Tl) it is almost 100% efficient up to around 300 keV and drops to around 65% at 3000 keV.

Choosing a CsI(Tl) scintillator will give better efficiency across the entire energy range, as the crystal has higher density and therefore better stopping power.
