Radhaz [Radiation Hazard] is a very important part of the general upper deck management of a warship with its many aerials, some fixed and some rotating. It also concerns itself with underwater transducers transmitting sonic waves - SONAR.

This file covers all the main points of that management in a modern heavy destroyer, a DLG, of  the 1960's

RADHAZ.pdf.  See also these pictures which were of the deck marking around transmitting W/T aerials.    

Pages 5 and 6 of the file should be printed and married together so that Part C [page 6] fits snugly with Part A [page 5].
