Th232 Gamma Spectrum
Thorium 232 Gamma Spectrum
The Th232 Gamma Spectrum, has many peaks stretching out to 2.6 MeV, and it can be tricky to identify the correct peaks. Detectors smaller than 2" x 2" may have difficulty seeing the higher end gammas, which means you are only seing part of the spectrum.
The following spectrum was recorded with a 3" NaI(Tl) detector with GS-1100-PRO and PRA 16. This spectrum was recorded with partial shielding, and therefore shows a prominent K40 peak at 1460 Kev.
Special thanks to Marek Dolleiser, for helping me with this spectrum, and providing some of the gamma peak data.
The following table contains the main gamma peaks present in the Thorium spectrum. Gamma peaks with intensity less than 1% have been omitted.
