We have three kinds of protection. Have a close look at the picture of the Mossbauer spectrometer on my profile page: you should see what looks like lots of grey bricks on the table left of the Mossbauer spectrometer. These are made of lead and are very heavy. You probably know heavy elements are good at adsorbing radiation: this is what the lead is doing.
We also have a Geiger-Muller counter which measures the background radiation by beeping at the frequency it detects radioactive particles. We use this to test the lab before and after changing samples. The person who changes
I try my best to avoid using the gamma rays, and when I need to use one to line up the x ray machine, it is in a lead case, inside another lead case and I have to wear radiation badge and use the Geiger muller tube too, and this is for a very weak one.
I was going to finish by saying the person who changes the sample also wears a personal counter like people in hospitals to tell them how much they have been exposed to the gamma rays. Low level is okay and known as background, but the counters will warn us when to exit the lab if there’s a leak.

Well, that didn’t work.
