AW: AW: AW: [ RadSafe ] News article from Belgium: Worker Critical after highradiation dose

Mike:

My (possibly not perfect) reading of the French texts gives me the impression that the interior of the irradiation room itself was surveyed by several ambient dose monitors and that somehow a defect of these was giving rise to the initial (false?) alarms and thereby contributed to the accident itself. However, they did not set off an alarm when the victim entered to inspect the irradiation room before locking again the door (why in the first place was it open on a Saturday, i.e., during weekend leisure time)?!? The fragments described by now are rather confusing ... and even faintly apt to rouse the suspicion of sabotage.

I expected the procedures to require the employee to use an ion chamber or
Geiger counter that gives an immediate result.
