Re: Tarcerco PED + Personal Electronic Dosimeter

By the way, I know the PDS crystal is about 1 cm further inside the housing compared with the PED+ tube because in the PDS's back there's a reference point for the gamma detector, circled in the photo below.

Tracerco PED + Personal Electronic Dosimeter

Hello there, This week I have no new sample to test, but I have a new device, the Tracerco PED+, Personal Electronic Dosimeter. Not sure if this section is for dosimeters as well , but…well, I hope it is. The PED shows you the doserate, accumulated dose since last reset and peak dose. You can also c...

Re: Hottest Sample so far - Autunite Crystal from China

Last sunday I wrote I would have attempted a Radon measurement with and without the Autunite crystal "sooner or later". In the end I couldn't resist and I started one the very next day. As I said before I am currently monitoring the bedroom of a house made of tuff. The room is at the upper floor of ...

Re: Tyuyaminite from Utah with Improved Graded Shield

Nice sample, beautiful spectra and well documented and presented job as always. This hard to pronounce Tyuyaminite i never heard before, so I even learned something new, thanks for posting! Actually I messed up the name writing Tyuyaminite instead of Tyuyamunite which is the correct name! Sorry for...

Re: Tyuyaminite from Utah with Improved Graded Shield

Nice sample. Could you tell us the weight and the dimensions? Sure, weight is approximately 140 grams. It's about 10 cm long and 3 cm thick. This is the spectrum from the PDS by the way, 3.5 million counts in 8991 seconds, average doserate 0.7 µSv/h. Linear Tyuyaminite - 8991 Secs - 05-10-19 - LIN....

Tyuyamunite from Utah with Improved Graded Shield

Hello there, My latest sample is Tyuyamunite from Vanadium Queen Mine, San Juan County, Utah. Natural Uranium is strong with this one….well, not as strong as the Autunite crystal I posted last week but still fun to test. DSC06960R.jpg DSC06964R.jpg This was also an opportunity to test my improved (b...

Re: Hottest Sample so far - Autunite Crystal from China

Well I am kind of radon-phobic, so probably mine is just irrational fear. Still, keeping uranium in the appartment is something I tend to avoid. I keep all of my low-activity samples that give any uranium peaks on the balcony. I don't have that attitude towards thorium though, I keep my calibration...

Re: Hottest Sample so far - Autunite Crystal from China

BTW, radon diffuses readily through thin layers of polymers from what I know, not sure if a plastic bag would be enough to contain it. A glass jar well sealed would certainly do the job though. That's right, actually Radon can penetrate through low density plastic. Sooner or later I will do the tes...
