ABSTRACT:
An apparatus for making radiographic pictures of an object submerged in a liquid comprising a substantially watertight housing having a reduced central section provided with a liquid displacing seal. The object to be irradiated is receivable in the reduced central section adjacent the liquid displacing seal. An irradiating camera is rigidly mounted in the housing. A sensitized film is additionally placed in the housing, oriented to receive radiation from the radiation camera after it irradiates the submerged object. In the preferred embodiment the reduced central section is a semicircular notch permitting irradiation of a partial section of the submerged object (see FIG. 1). An alternative embodiment has a hinged circular reduced central section permitting irradiation of an entire cross section of the submerged object to be irradiated. The apparatus can be transported underwater, mounted and actuated by a single operator.
