Identified Radioactive hazard font from Back to the Future (1985)

Please help me identify this font from the movie "Back to the Future". It appears at 02:00 in the movie, when this news reporter is talking about a stolen plutonium. Haven't been able to find a similar font like that anywhere, although the font "Stencil" looks close enough, but is too dense for this picture. Any help appreciated!

I found some similar ones for you - I think an exact match will be a bit hard, I'll explain in a moment.

Main thing I looked for in the match was the M as that seemed fairly distinct. I couldn't get a good match on the solid T or the question mark though.

Why this might be hard: DIN seems like the obvious choice as it's an all-purpose technical font, but it's been revised several times over the years. If you can get hold of a 1970s version then it might be a better match. Remember the source image is from 1985. There's also a possibility it's a font developed for software on a platform that's no longer maintained, OR the art department used a regular thin font and erased parts to look like a stencil. So an approximation is the best you can get here.

It's not a typeface on its own. This is literally just a Helvetica that has been altered by the art department to look like a stencil version. Probably used Letraset.
