When my kids were little, we had glow in the dark pacifiers that lasted ALL NIGHT. I still don't know what sorcery was used to accomplish that, but if any of you have little ones, the MAM brand is what we used. Being able to spot the pacifier in the crib at 5am was a huge help some nights.
And now my kids each have an extra eyeball, which has proven very useful indeed.
I have a tritium keychain that makes it delightfully easy to find my dropped keys in the dark garage.
And some GMO petunias that glow 24/7. https://www.instagram.com/p/C8_Dgqvuq2C/
Looking for seed. Only seeing little plants (which ship terribly and cost way too much). Petunias are dead easy to grow from seed.
Tritium-lit pacifiers sure sound like a legitimate 1950s atomic age product.
Not sure what the modern one are, but they will still glow in the morning hours. They are very very handy!
There's a youtube channel from someone who finds and reports frivolous radioactive products to the NRC, getting them banned. It happens even today.
Hey I bought this stuff on amaz. It's good. Made glow plastic, glow goo
Would Strontium-90 make it glow ~permanently?
Huh, it very well might. 90Sr is a beta emitter, which should excite phosphorescent materials nicely. Even better, it decays into Yttrium 90, and Yttrium Aluminate is also phosphorescent (it's also the YA in YAG lasers). Anyone have some spare 90Sr we can test this with?

Depends on your definition of "permanent"
With enough Strontium-90 involved, that might not be very long indeed.
