Radiation Detection

I just received the PDS-100G without software. Many thanks for all the info in your forum regarding this nice device. I would appreciate any help in obtaining the PDSmass Software. Thank you! Me too. I'd love a copy of PDSmass as well. I have a version which is very cut down and next to useless. I ...

Nice work Massimo, this weak sample is not an easy task ,yes more lead is needed but you did it! Try to use the whole sample "wrapped" around the detector in a 4Pi geometry, doing this improve a lot the detection. Yeah, I have a couple of ideas for a better geometry next time, also I am going to tr...

Hello there, This weekend I tested a sample of Italian north-west Alps’ soil sent me by Ciro (Cicastol). First of all thanks Ciro! The sample is about 300 grams of soil, it has contamination from Cs137 dating back to Chernobyl accident and comes from one of the areas of Piemonte most affected by the...

Thank You Jonathan, I'll be after this tube before too long!

Well that's nowhere as pretty as the autunite on the other hand :(

Yeah, not nearly as pretty, still picking samples walking down the road is a lot more fun than an online auction!

Hello Massimo, Got my radon meter (the same gray AirThings one). I got very low readings after the first 24 hours or so - just 18 Bq/m3 long-term average. Manual says accuracy gets within 20% after a week and within 10% after a month, so I guess this value is pretty inaccurate, it needs more data t...

Thank you Stefan! I didn't know about that setting. I did long measures with the PDS but always pressing "resume" every 999 seconds. Yesterday I put 000 seconds and it worked like a charm. Like that it's much more comfortable. The fact that the saved spectrum will never show an acquisition time long...

Hi folks, I finally learned how to use the software. Before getting into details a few advice for those who might be interested in the device which can save you a couple of days of fruitless attempts and a growing sense of frustration: - The user manual will advice you to set the logging option "Int...

It seems to be a great device : hope to see it dealing with other hot samples :-) It will for sure, At contact it gives higher readings than the PDS, but that's probably not very significant. By the way, that's the spectrum of the "multisample" from the PDS. Ony 15 minutes, less than a half million...

So I am not the only one going around with a PDS 100G always in my pocket! Talking about Tc99m you could be interested in this video https://www.youtube.com/watch?v=Mj0HDN82Pfo Another example is the dose from I131 people get from Thyroid cancer therapy, I couldn't believe it when I learned it, it m...
