Kromek Kspect MCA, basic and told hundreds £ if wanted the Multispect software with isotope identification.

Conclusion

While I hoped that lower FWHM would result in rapid isotope detection and superiour performance at low levels in lead pig.

The following became apparent:-

  • 5x5x5mm detector takes far longer to recognise Cs137 contaminated soil than 2 inch nal (Ti)
  • Longer duration runs overnight should offset to some degree the previous comment and hopefully as lower FWHM should make data easier to check.
  • Multispect software may be worth the money- no free trial and nothing to temp us to spend hundreds.
  • Kspect software cramped-Theremino MCA will be pressed into service.
  • Imetry software on ios seems far more responsive than Kspect side by side-going mobile this is my choice of MCA
  • Neat charger-shame un shielded pins
  • Digital output could be polled by linux
  • Analogue output far more versatile
  • can be self powered( from Rad Angel battery) on ipad etc
  • Urban prospecting without raising concern.
