I don't know about others. For me this is just a new set of techno toys to get to know and play with! My 18 yr old son recently not-so-patiently explained to me that alpha particles are stopped dead by just about anything. We were 'discussing' whether a nuclear bomb going off on top of a silo

Re: [neonixie-l] Radioactive Nixies - Study

IIRC, correctly calibrated CRT television sets and computer monitors did not emit X-ray at all. Nor any other kind of harmful radiation, for what is worth. The warnings were related to the operation of the HV rectifier (in times of the vacuum ones, 1B3 and the like) way off its HV maximum

Those ZM1000's were made in a year ending in 6 and/or 7 according to the date code. I'm guessing 1976/77. On Tuesday, March 14, 2017 at 5:59:46 PM UTC+1, David Speck wrote: > > They are labeled as 3H, for tritium, so they would have a 12 year half > life. Any idea how old they are? > > Dave >

Anyone know how the radiation "hazard" of nixies compares to Xrays produced by color televisions/computer monitors that used CRTs ? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving emails from it,

That kit doesn't look too bad, but 55$ for a Geiger Counter without a display? For 39$ without a gm tube you could get this one https://sites.google.com/site/diygeigercounter/buy-the-kit-1 Many tubes are supported, gm-tubes (SbM-20 is a good choice) on ebay. And...for "just experimenting"

They are labeled as 3H, for tritium, so they would have a 12 year half life. Any idea how old they are? Dave On 3/14/2017 12:03 PM, franetic wrote: Just as a curiosity, I have (I had) some boxed ZM1000 nixies branded by RTC (France). See attached photos. The box has a label warning about

So how should I do to properly test all old instruments and tubes that I buy to check that they are safe, free from harmful radiation, is there any reliable equipment that don't cost an arm and a leg that I can use at home? I'm not particularly afraid but if there is an easy way to check then

Hi This might be a little off topic or irrelevant, but maybe someone is interested in it too. One of my hobbies aside nixies is technology related with radiation and nuclear (geiger counters, etc). Today i was sorting my nixies into boxes and held a B-5092-A from Burroughs, as i spotted a
