Safe Practice
Exposures to microwave radiation above the recommended limits are most likely in the immediate vicinity of the antenna when it is stationary. When the antenna is rotating, as required for normal operation of the radar, average exposure is below the recommended limits, even at points as close as one metre. Some radars are designed to prevent microwave emission unless the antenna is rotating.Other models,however,lack this safety feature.In these cases some care is required on the part of the operator to prevent unnecessary exposure of personnel.Operating procedures should be adopted which ensure that no microwave radiation is emitted except when the
antenna is rotating.
A rule of good practice which applies to all small
marine radars is that equipment should be turned off
when not required,particularly in areas of high popu-
lation density (e.g.at dockside).
