I’m not an expert by any means, but aparently there is an extremely lucrative market for pre ww2 scrap steel.
Because that iron was made into steel before nuclear bombs and nuclear meltdowns started on earth, the steel emits lower baseline radiation.
That steel is vital for particularly sensitive electronics, mainly stuff like sensors for electron microscopes and medical devices.
Because we have so severely raised ambient radiation in the atmosphere by refining radioactive material and blowing it up, disbursing it into the atmosphere, we can’t make steel that is suitable for these applications anymore. We depend on repurposing pre nuclear age steel, which is running out. Fast.
The moon has a shit ton of iron that is exposed to solar radiation, but has not been exposed to refined terrestrial radiation.
If we bring refined radioactive material to the moon, we are likely to contaminate the iron there too.
We can still make radiation free metals. It’s just way more expensive than recovery of pre WW2 metals.
Bringing a nuclear reactor to the moon wont contaminate the iron there unless you detonate the reactor near the surface and even then it will only contaminate the iron directly below the blast. The reason steel on earth is contaminated is because we use air that is contaminated with radionuclides in the manufacture of steel. No air on the moon means no contamination.
Also the radiation has fallen pretty much back to background levels since we stopped atmospheric testing so modern steel is generally radiation free. Only the most sensitive steels need to be low background steel. Another 50 years or so and we should be back to baseline.
Can someone explain why this is a problem?
Please use small words as I am dumb.

Hope that helped.
More specifically I think it’s pre-WW2 scrap steel from underwater.
Anything exposed to the atmosphere received some radiation but scrap steel from sunken ship are not contaminated.
