New Magnet-Powered Monitor Installed In Nuke Waste Sites Could Survive 100 Years

Of course, that raises the obvious problem of creating a 100-year timer to release the magnet.

How about a 555 timer, come on guys keep it simple?

They didn't solve the problem, they just moved it, and not very far.

A 100 year timer/battery to monitor a pile of hot refuse that has a half-life duration of several thousand years.

After 100 years of radiation, what happens to these magnets, assuming that they don't get above the Curie temperature and lose their magnetism anyway.

I cannot see that this will solve the problem, the nuclear waste is highly radio-active for several thousands of years, whereas this monitor will only last for 100 years, if that, remember it is very hot down there?
