Bill Park's gives the advice I would give.  Radon mitigation systems are a common installation in many buildings and usually no big deal.  However, I would have one further recommendation:  run the installation plans past facilities and past a consulting industrial ventilation engineer to be certain there is no local exhaust system in the lab that would be impacted or any high temperature equipment that could be back drafted.

The radon mitigation installers are used to dealing with ordinary homes and public buildings.  So get another expert opinion on the effect of the proposed system on the existing ventilation systems and equipment in the lab.

And once in a while we've run into foundation and wall breaching issues.

If there are reasons the ordinary radon mitigation system can't be installed, a really good engineer specializing in industrial ventilation (don't let an HVAC engineer anywhere near this project) will be able to design an internal system that utilizes your fume hood or other local system duct work.  It is definitely not the preferred way to go because there are always balancing problems when exhausts with a different velocity and purpose are branched into an existing system.

Radon mitigation systems are routinely installed to relieve the gas build-up. Check with an IAQ company for assistance.
