IONISING RADIATION-OFFSHORE

Every exposure to ionising radiations does involve a certain degree of risk to health and, as these radiations cannot be seen, heard or felt, they present a special hazard. However, given our understanding and control of ionising radiations they can be used safely.

The first section of the video deals with the three factors that provide protection from radiation, i.e. shielding, time and distance. Diagrams are used as an aid to understanding the practical issues involved and the reasoning behind them. The video continues by showing in detail two typical offshore uses of ionising radiation - a wireline logging operation and a weld inspection.

Although these two techniques are quite different the safety aspects of both that concern non-specialist personnel are similar. The video examines these operations from both sides and provides an understanding of how and why the ionising radiation sources are used emphasizing and demonstrating the safety aspects of each procedure.
