I’m pretty sure everyone is allergic to having their skin and lungs rubbed with mica.
Moon dust is functionally a lot like asbestos. It is composed of a sizeable amount of tiny shards of rock that aren’t great for your lungs.
Isn’t moon dust just sand?
It’s sand that has never been exposed to water or oxygen. This leaves various reactive chemicals on the surface that would normally be broken down. The lack of water also means the particles haven’t been smoothed off as much. They are sharp and spiky.
The combination of these effects makes the dust quite unique, compared to earth dust.
Sand, but sharp due to a lack of water erosion, and formed mostly from asteroid impacts and thermal cycling. So it’s more like glass dust. It’s possible it has similar effects on lungs as asbestos, but we don’t know for sure.
Not being allergic to finely graded rocks that have been bathing in radiation for billions of years seems more unlikely.
