A radiation monitoring system for the L3 experiment at the Large Elect
ron Positron (LEP) collider is described. This system was installed in
the L3 detector in April 1993. It provides information on the instant
aneous and integrated radiation dose in the vicinity of the L3 silicon
microvertex detector and time expansion chamber, and since April 1994
it has also provided trigger signals for the LEP beam dump in the cas
e of large instantaneous dose rates in the L3 central tracking region.
