You won't get these in Poundland......

Interesting.

The article mentions placing the diamonds near
a "radioactive field". I didn't understand that.

You did better than me, I didn't understand any of it.

Is a radioactive field similar to a magnetic field? i.e. A source.

When carbon-14 decays it emits beta radiation, which in essence is high energy electrons. It's not clear from the vid but I would imagine that they've found a way to make the diamond into an electron pump using these energetic electrons thereby generating a current. So the radioactive diamond is creating its own electrical field.

Thanks Mr Bongo playing physicist avatar!


(I did't think "radioactive field" was a thing.)

Diamond is a pure form of carbon, very dense and very hard. Nuclear reactor moderators are Graphite - carbon. What they appear to be saying is they bombard spent reactor graphite to create an artificial diamond. And this creates a charge; which when in the presence of a radioactive source, will generate a Voltage, which when applied across a load - pacemaker etc, will power it. I think! A quartz crystal generates a voltage at right angles to a force applied to it. It may be analogous, given diamond is also termed a crystal.

It should have said "radiation field" really.

I dunno what sizewell's been smoking though. Trump science!

Also radioactive moderator is probably the least of the waste problem, no?

In terms of toxicity and ease of storage, yes, but there's a lot of it lying about. A piece of paper is a pretty good beta radiation shield so encasing it in diamond and making a battery which lasts several lifetimes is safe and exciting. Current nuclear batteries are plutonium powered and that's horrible stuff.
