> when the LHC runs, the chambers housing the detectors experience intense radiation

I thought that it was very energetic but low intensity radiation (outside the main tunnel). Does anyone have more data about this? How many "normal radiography" equivalents do you get for standing there for a minute?

I took a tour of the ATLAS experiment last year, and the guide said that if the LHC was operating, the radiation where we were standing would be fatal in seconds.

Anywhere around the accelerator you are going to have massive cyclotron radiation ( ie. the photons emitted when you coerce of near light speed proton out of a straight line).

In addition, at the detectors themselves, you have all sorts of radiation from the collisions. Muon, gamma, etc.

The author does pass on a good point, the biggest danger is oxygen deprivation from liquid helium, argon, and I assume Nitrogen ( though not mentioned ).

Well no, the biggest risk is falls according to a CERN safety presentation from this year:

(Handling is pretty vague though, and it was hard enough to track down this paltry statistics, so I'm glad falls won)

But oxygen deprivation is probably the biggest "exotic" hazard.
