In my collections are a half-dozen unusual Trinitite samples. This series will examine them using all the tools currently available in the Home lab. Various sensors will be used, as well as a few

Steve- here's the data on the two Zircons, (for some reason my eMail won't attach them). Geo

Not back then Taray, this was 25 years ago, before my nuclear radiation hobby. Back then the hobby was ionospheric ionization and its effects on radio waves, so the gear was different. Geo

Nice work and great re-use of available materials. [email protected]> wrote:

Geo Did you collect any rock samples ?or did any handheld measurement? . Anyway I find it rather difficult on family trips. The heat and humidity is sometimes unbearable in SE Asia. Taray

Good on thorium, it is more rare where I live. Uranium is everywhere tho, some much more than others. There is a map op Radon distribution for whole US, by the US Geological Survey, shows radon

No worries I am in Malacca. You told me once you have been to Singapore Recently discovered Malaysia has a rich source of thorium.. not through local news but through my own reading and interest in

Yes that is what I mean. Mine is set op so rays are at 90 degrees to detector, the samples is in the rays but set at 45 degrees so the new rays go to the detector. our yield should increase many times

Geo This involves moving the detector slightly away from the sample and realigning the specimen at an angle such that the incoming beam and detector are looking at the same sample broad

Correct and there are other parts that can only be purchased at Amptek. Total cost for mine, just for all parts was $1800 USD plus shipping, and no housing etc.Geo

Sorry Taray, I would if I could. It's not something I do normally. What city are you in Maylaysia? We visited there when we sailed the strait of Malcca.Geo

It looks good Taray, one thing to try, repeat the setup but put the sample away from the source, sort of like a mirror that the source and sensor are both looking at the same surface?Geo

Charles Ok then i put it ?on hold till I get more details Thank you Taray

Sorry if I gave the impression that the working system costs $1200. That is just the components off eBay and you take all the risk. Of course then they need to be integrated and configured. I have

Geo Sorry for the late reply Thanks for the tips Anyway if you can assemble a Charles style setup ,I will happy to buy it from you. 240 V and total cost $1200 Shipping to Malaysia Taray

Hi guys This is my X-ray setup My x ray generating tube sits within a cylindrical X-ray collimator This collimator protrudes into a cardboard box containing my X-ray detector and X-ray signal

Steve D's lump vs Geo's blob.XRF purity? Fe investigation. 30kVp-25uA. Si-PIN. run times similar, time adjusted as needed so Fe peaks are same height. Difference in hump is aluminum filter

Geo, Pu is best detected with an HPGe detector or via a Fildler using Am-241 as the surrogate. For an alpha detector anything over 20 dpm alpha would go to an alpha spec to determine if it was Pu or

Great Trinitite gamma spec charts by Pittauerrova et.al. Link http://www.radioaktivitaet.uni-bremen.de/Seminar/Trinitite.pdf There is a glaring error in one chart, can you find it? Geo

Will do Dud, thanks I have some of each and will look at them.Have you seen anything about plutonium detection in trinitite that you can share?Geo>K0FF
