Abstract

In accordance with the principles of the present invention utilizing a first radiation monitoring module, radiation information associated with the first radiation monitoring module within a tunnel is wirelessly transmitted to a second radiation monitoring module. The second radiation monitoring module is able to receive radiation information from the first radiation monitoring module for relay of the received radiation information to a central monitoring system. The radiation monitoring modules of the present invention allow long term monitoring of a tunnel'"'"'s radiation levels with maintenance simply requiring replacement of a non-operational tunnel monitoring module by a robot.
