Title:ROC BOMB POWER INDICATOR AND GROUND ZERO INDICATOR (part 1) [Main Title]
Film Number:DRF 7120
Other titles:
Summary: Use of simple monitoring equipment for the direction and strength of nuclear blasts.
Description: The three man team arrive at their ROC monitoring post, a bunker located down a shaft. The film shows how the bomb power indicator (BPI) is set up, and how the ground zero indicator (GZI) is prepared by pre-exposing several sets of "printing out paper" charts with a grid, the first set being placed in a pinhole camera device mounted above ground. In a simulated attack, the BPI reading is taken (logged on a form dated 31/9/84 in this film) and reported back by radio/telephone (?) to the group operations room. After one minute, one of the team goes up to change the detector charts in the GZI. The position and elevation of the blast given by the chart is noted and reported. A team member demonstrates blindfold the routine changing of the charts (needed up to twice a day in the summer due to exposure from daylight).
