Four years seems like a bizarre number, and the sources aren't linked to. I feel like this may be AI generated nonsense

Another source for estimated radiation exposure on Mars: https://phys.org/news/2016-11-bad-mars.html

A newer study on the depth you need to be under martian soil: https://eos.org/editor-highlights/life-on-mars-estimating-radiation-risks-for-martian-astronauts (spoiler: trying to live at a depth of 30cm is bad)

Interesting study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3797711/ (spoiler, you be fucked.)

I read and linked some things and my 3am napkin math didn't produce any valid numbers in the 4 yr range. (My first thought is that radiation is going to the the least of your problems when visiting Mars, TBH.)
