[Opinion] prefixOpinion (op-ed) articles must use [Opinion] prefix before the title. Opinion articles refer to articles that their publisher doesn't explictly endorse.
Country prefixCountry prefix can be added to the title with a separator (|, :, etc.) if the news is from a local publisher who doesn't clearly mention the country.

If it’s a small battery intended to be used a long time, pretty much a guarantee these are going to end up in the general landfill waste stream.

I wonder how much contamination one of these will cause if it goes through a waste incinerator. If they have 50 Curies of activity, that’s more than a million times what’s in a smoke detector.

They’re probably going to be used in medical devices like pacemakers. So they’ll be in the land but not necessarily a landfill

There’s a lot of radioactive thorium to be found in coal ash leftover from power plants. I am not worried about this.

[–] Cethin@lemmy.zip 2 points 1 year ago

Eh, it's likely not an issue. There's radioactive material in water runoff and all kinds of places. A small amount is not noticeable. Even in the worst case, these aren't an issue. If they can be near your body 24/7 without causing problems, them getting spread out into even smaller pieces can only be less significant than that.

People are too scared by radiation. It usually isn't an issue and you're constantly interacting with it. It's only in very rare circumstances where you need to worry.

For comparison, the Betacel boasted 25 microwatts per cubic centimeter, and this Betavolt battery appears to have 88 microwatts per cubic centimeter. This will also have a longer lifetime also.

The Betacel was successfully used to power pacemakers. I suspect there will be more applications for power sources in this range today.

Casio G-Shock / Fallout Collab?

[–] deegeese@sopuli.xyz 6 points 1 year ago

Casio F-91W☢️

[–] Mvlad88@lemmy.world 2 points 1 year ago

I had to go trough way too many communities to find the first Fallout reference.

[–] skozzii@lemmy.ca 5 points 1 year ago

I wonder what it tastes like...

[–] possiblylinux127@lemmy.zip 3 points 1 year ago (1 children)

I want this in a four function calculator

[–] chonglibloodsport@lemmy.world 9 points 1 year ago

Why not Solar? I have fairly recent Casio (FX-260 Solar II) and it works in dimmer lighting conditions than I’m comfortable working under anyway. Under normal lighting (for being able to see while doing math with pencil and paper) it’s rock solid!

Perfect. You know how hard it is to find replacements for those? Now I can just have my watch be nuclear powered and not have to worry about that. Only thing I have to worry about is having my arm mutate into getting time control powers.
