Yes! This is pretty good! But i would look over some of your grammar,
You put : But i think that you should does not eat food grown in space because of radiation
I’d put : missions, but i personally wouldn’t recommend eating food grown in space because of the radiation it could hold.
You put : radiation is bad because radiation can damage the dna in our cells
I’d put : If you didn’t know, radiation is not a good thing to consume of any way because it can damage the dna in our cells.
You put : it can even cause radiation syndrome which happens when you get too much radiation
I’d put : Too much radiation can lead to radiation syndrome, so it’s best to be very careful when interacting with it.
