Re: Chernobyl fungus as a radiation shield?
Both this and the article on selenium are skirting the issue of attenuation. A material might have 'radiation absorbing properties' but that is normally expressed as proportion of the flux (?) at a given wavelength that is absorbed at a particular distance in the subject material.
Most popular presentations and almost all scifi gets this wrong. There is a reason the dentist puts a ten pound bib on you before a (very low dose) xray. It takes that much material to absorb the radiation in question.

Any metaphor will tear if stretched over too much reality.

Exactly! There’s good physics saying that this optimism about solving the radiation environment problem is fatuous.GCoyote wrote: ↑Wed Jul 29, 2020 2:31 pm Both this and the article on selenium are skirting the issue of attenuation.
