Talk:2321: Low-Background Metal

I can't help but notice that the basic premise of this comic is very much like the reason for going back to 1970 in Avengers: Endgame, when they needed more Pym particles for time travel. I wonder if Randall re-watched it again recently? — KarMann (talk) 17:10, 17 June 2020 (UTC)

Drawing

There's one leg of the time-machine missing from the 3rd panel. (or is it the side of a base?) --162.158.155.126 19:57, 17 June 2020 (UTC)

Mined lead

Pb-210 (half-life 20.4 years) is a decay product of radon, and thus accumulates everywhere that is exposed to the atmosphere or where radon seeps from the ground. I suspect it could be a contaminant in lead from some lead mines, but wasn't able to find any references ShadwellNH (talk) 20:00, 17 June 2020 (UTC) Paul

One use only?

The way I understand it, the time machine is one-use unless you find other Low-Background Metal. If you find it, you can make more trips. It would appear that the trip is successful. --188.114.103.129 01:31, 18 June 2020 (UTC)

Real life use of this lead?

Does anyone know whether there is any truth whatsoever to scientists using lead from sunken ships to shield delicate equipment? Obviously not time machines, but there are some pieces of equipment that might be sensitive to radiation.

Also, would lead that was in the ocean actually be safer from nuclear fallout than lead that was underground and mined after the nuclear testing ended? 108.162.216.172 03:31, 18 June 2020 (UTC)
