From my experience, it's really key to get proper protection before you even attempt that area - a solid protective suit like the ssp-99 ecologist makes all the difference. The radiation pockets there will mess with your head pretty fast so swing by the traders near yanov, and grab some anti-rad meds plus those blue medkits before heading out.

Something interesting - if you check out forester and do his burnt fuzz task first, you'll get this sweet goldfish artifact that gives you decent psi protection which really helps in there. When you're actually dealing with the hot zones, make sure to pop those psi-blockers before your display starts going weird, and keep an eye out for those purple glowing spots since they mark the worst radiation areas. Best approach is usually to sprint through the narrow parts instead of trying to loot while you're getting cooked.

Worth mentioning that nighttime runs are usually a bad idea cause that's when emissions tend to kick up. If things get too intense, there's a portable lab to the southwest where the radiation drops off quite a bit - makes for a good fallback point if you need to catch your breath and let your gear recover.
