Another bummer. Been trying to load DECAY_v4 since last night. No go. Install program insists the program be loaded to PROGRAM FILES, but WIN10 wont let me mess with that folder, even tho logged in as

Probably not much on the metal surface helping heat, because there there are rubber feet on the bottor to allow airflow on the bottom surface. You can however place a goodly chunk of aluminum on the

Geo Ok will do it ... As you can see in the pic,I placed the detector on a ?metal surface I hope it also acts as a heatsink? Taray

Your sensor box and RAPCAP (AmX6 ring) are in good geometry. The case of the GEO-1-2-3 is also a heat sink so make sure there is airflow around it.No blower needed, just natural air. The case gets

Super work Taray. We look forward to your work because you have access to samples we usually don't see here! Geo To: [email protected] Sent: Monday, September 28, 2020 6:00:07 AM Subject: [XRF] Si

Oops Error in BIPP pic Here it is .. Also managed to correct Am241 orientation and added 2 more. These exciters are flat-top unlike the regular button like regular ones I used before. Really sticks

My version is 3.0, 1999 I find it easier to use.We're talking about Pu-239 correct?:Photon Emission Products: Pu-239 Fraction Energy(MeV) 0.000476 0.112910 0.044141 0.013600

What version? Hacker’s Rad Decay Ver 4 shows these yields much lower 238 = La 3.79, 239 La 1.57. Other references also support the lower yields. Dud Sent: Sunday, September 27, 2020 3:50 PM To:

Now on to quantification. It takes the calibrated sample ~3 times longer to reach the peak height of the BLOB when using the 17.22 keV line. (C)George Dowell 27SEP2020 Geo

Geo, Double check those yields. They look to be about 3x too high. Which program were you using? Dud Sent: Sunday, September 27, 2020 12:31 PM To: [email protected] Subject: Re: [XRF] Trinitite

From Prof. C. Hacker's DECAY program, the likelihood of Pu-238 decay producing a Ka1 X-Ray from it's progeny U-234 is 11.57% Photon Emission Products: Pu-238 Fraction? ?Energy(MeV) 0.000473
