Re: Low Background Steel. When you say "work with low radiation hardware", it gives the impression you're talking about radiation sensitivity (damage), which is ofc not the case: hardware is much tougher than people, and modern steel is completely safe. We're literally talking about "background". If you have steel plates in your neutrino / double-beta decay / axion detector, where your signal may be 4 events per month: you simply cannot have Cobalt-60 gamma rays appearing at 2 events per month. Even though Trinity was 14.5 half-lives ago, and 99.996% of Co-60 has decayed, the problem is that Avogadro's number is HUGE. A single microgram of Co-60 in 1944 will yield 4 event per second in 2021. That is huge background.

@KatyaAbc575 they also use low potassium glass in the phototubes too, and those experiments 4000m down a mine shaft? The rocks are full of thorium and all that, so they basically need to make it a clean room. In a working mine. Not easy. (I've never worked on one of those...it's just hard...you got to earn you neutrino Nobel prize). Look at Ray Davis. He detected 40 argon (from neutrino + Cl) atoms per month in a swimming pool full of cleaning fluid, when the Sun was supposed to make 60 (afaik). 40 atoms, in a pool. Have you ever tried to clean a pool?).

Re: A tank of hydrogen ions. The electric force is really strong. To confine a single gram of protons into a 1 meter tank requires 12,000 megatons of energy. A gram of electrons?...that's around 40 Petatons of nukes (goes a Q^2/R).
