Hybrid pressure vessel

The disclosed invention comprises one or more hybrid metal-composite pressure vessels e.g., 1 (FIG. 1) or 100,200 (FIG. 2), designed for deep water application of radiation sensitive equipment, where the hybrid pressure vessels comprise a combination of metals and non-metals. A source of radiation may be disposed in one of the two hybrid metal-composite pressure vessels and a radiation detector disposes in the other hybrid metal-composite pressure vessel. A radiation beam is less attenuated as it passes through the non-metal parts of the hybrid pressure vessels and the intensity of the radiation reaching a radiation detector is higher than if it were to pass through the metal parts of the housings.
