Re: Filter isotopes

Coal will adsorb anyhow the organic species contained in rain. For collecting species in ionic form, as cations (metallic species, Cs (137!), ) and anions (nitrates, chlorides, iodides (J131!), phosphates, sulphates, etc.), I would recommend the use of ionexchange resins. These are available for cat...

Re: Intune Software - A handy tool for beginners

Hi Steven, Thanks for this information. I am going to try this diagnostic software Some months/weeks ago I have started with blank measurements and with some samples which should give a spectrum, unless the backgroud radiation. No shield available sofar (Project in planning). NaI Bicron 3M3/3P, Canb...

Re: How far can electron radiation penetrate flesh?

Hi Felix, Indeed a lot of incidents were reported with this equipment. Main problems were related to using the wrong software and also the failure of hardware resulting in a wrong position of the selector for X-ray/electron beam exposure. These failures resulted in settings where patients were expos...

Re: tritium

Thanks sgt_bear for your comment on this issue. We could try to get more serious and scientifically based from now on. The radiological toxicity of T (3H) (in the form of tritiated water: HTO) can indeed regarded as relatively low, as compared to isotopes as 32P, 90Sr or beta emitters as 131I and 13...

Re: tritium

I would like to refer to my earlier postings about the chemical and biological effects of tritium. In fact all organisms have been exposed during ages to tritium which is a naturally occurring isotope while it is generated in the atmosphere, mainly as HTO. Organisms have so many repair mechanisms to...

Re: Concerns about Belgian Nuclear Plants

The concerns about a nuclear catastrophe in the Belgian nuclear power plants are increasing. More and more political pressure is growing and legal steps are proceeding in order to force Belgian Authorities to shut down the plants where problems are most severe. Recently an initiative has started for...

Re: Radium vs Tritium

Fact is that biosystems and living organisms have been exposed to cosmic radiation from origin of life on. So the exposition to D (Deuterium) and T (Tritium) is a part of life and many mutations, not always bad, are the consequences. Most uptake of T is in the form of HTO (formed by cosmic radiation...

Re: customs fee to get stuff from Australia to Germany

Hi, Within Europe (including Sweden) there are common rules for VAT and custom costs. When I buy books or CD's from UK shops I don't pay for VAT or extra costs too. When the Brexit will be official, then we will have to pay additional costs and VAT when buying in UK, unless trading rules will be agr...

Re: customs fee to get stuff from Australia to Germany

Hi Kolja,
Addtional Note: German Zollamt calculates the MWSt of 19% over total billing from Steve, so net value of apparatus+postage/handling.
Actually what you payed after conversion to EUR

Re: customs fee to get stuff from Australia to Germany

Hi Kolja, I am living in the neighbourhood of Aachen and I recently ordered equipment from Bee Research. Steven informed me before that his prices are without Australian VAT (Mehrwertssteuer). I received the GS-1100 PRO from Steven by end July. The Deutsche Post sent me a letter and informed me that...
