Automated radio alarm

Automated radio alarm is a radio station in Fallout 4. It can be found by activating Radio tower 3SM-U81. The signal leads south-southeast of the tower to the Mass Fusion containment shed.

Characteristics
As the message suggests, there are high levels of radiation in the facilities, with over 60 rads in some small areas.

To get to the sub-level, go into the mag locked cage. Take the fusion core out of the reactor and then turn around. Directly between the loading ramp and the push cart with two barrels on it there is a trap door that leads down into the sub-level. In the sub-level there are a lunchbox and a circuit breaker. The broadcast stops upon flipping the circuit breaker.
