Details


INTERNAL ASSEMBLY: Includes NOS PMT tube optically coupled with NEW 25x25mm NaI(Tl) scintillation crystal. Same crystals are normally sells for hundreds of dollars when purchased new. The PMT is wired with internally installed high voltage power supply. HV is stabilized, filtered and adjusted for the tube. Signal from PMT anode followed with pulse amplifier. Pulse level and duration at the output are compatible with Line/MIC input of sound card or iPhone. The electronics powered with internally installed rechargeable battery. The unit can be charged with 5V DC adapter. Battery capacity is enough for portable operation during 4-6 hours.

With the device you can test and identify gamma emitting isotopes, perform food test for radionuclides, test minerals, search radiation and etc. The spectrometer with freeware MCA software can successful detect Cs-137, Eu-152, Ba-133, Co-60, Am-241 and more dangerous nuclides. The unit has measured ~10% FWHM resolution at 662keV. Recommended to operate with 24bit audio cart on computer. Due to hardware and software limitation please test samples with activity up to 1000 CPS, if your sample has higher activity you can increase distance between the sample and the spectrometer.

The item is fragile! NaI(Tl) crystals cannot be used in fast changing temperature enviroment. For calibation you have to hold weak calibration source of Cs-137 that can be obtained legally from companies like Spectrum Techniques or Ritverc. We'll help you for the first setup with MCA software if you need technical support.
