Radiation measuring apparatus
First Claim
1. Radiation measuring apparatus comprising a sensor assembly including a sensor shrouded within a pad assembly that is transparent to the radiation to be measured and which facilitates mounting of the pad assembly on a surface, the pad assembly being disc-shaped and having a diameter less than about 50 mm, the sensor having a scintillating body which absorbs the radiation and converts it to light and means for measuring the intensity of the light emitted by the body and thereby indicating the amount of radiation to which the body had been exposed.

Abstract
Radiation measuring apparatus includes a sensor assembly (10) including a sensor (16) which includes a scintillating body (30, 30'"'"') that absorbs radiation to be sensed and converts it to light. A measuring device (38) measures the intensity of the light emitted by the scintillating body and thereby indicates the amount of radiation to which the body (30) has been exposed. The sensor assembly may also include an optical fiber (12) by which the light emitted by the scintillating body is conducted to the measuring device (38). A plug (14) located on an end of the optical fiber remote from the sensor (16) is adapted to be detachably inserted in a connecting socket (40) of the measuring device (38). In this way the sensor assembly (10) is readily exchangeable for a new assembly.

17. Radiation measuring apparatus comprising:
-
a sensor assembly including a sensor having a scintillating body made from Zinc Cadmium Sulphate-Ag powdered particles reconstituted into a thin flat scintillating disc which absorbs radiation and converts it to light, the thin flat scintillating disc being mounted on a base disc; a flexible optical fiber overlaying a portion of the base disc so that a first end of the flexible optical fiber is positioned adjacent the thin flat scintillating disc, and wherein a mirrored surface, positioned at an angle relative to the base disc, overlays the thin flat scintillating disc so as to direct light emitted by the thin flat scintillating disc into the flexible optical fiber, and further wherein an opaque molding layer shrouds the thin flat scintillating disc, angled mirrored surface, and the first end of the flexible optical fiber; and means for measuring the intensity of the light emitted by the thin flat scintillating disc and thereby indicating the amount of radiation to which the thin flat scintillating disc has been exposed. - View Dependent Claims (18, 19)

20. A sensor assembly suitable for sensing radiation comprising:
-
a flexible optical fiber having proximal and distal ends, a plug connector at the proximal end; a sensor at the distal end, the sensor comprising; a scintillating body made from powdered particles reconstituted into a thin flat scintillating disc positioned adjacent the distal end formed of a material which emits light when the scintillating disc is exposed to radiation; a base disc on which the thin flat scintillating disc is mounted, the base disc facilitating attachment of the thin flat scintillating disc to a surface, and wherein the flexible optical fiber overlays a portion of the base disc so that the distal end of the flexible optical fiber is positioned adjacent the thin flat scintillating disc; a mirrored surface positioned at an angle relative to the base disc so as to direct light emitted by the thin flat scintillating disc into the flexible optical fiber, and a molding layer that shrouds the thin flat scintillating disc, angled mirrored surface, and the distal end of the flexible optical fiber, the molding layer being transparent to X-ray radiation, but being opaque to light emitted from the thin flat scintillating disc. - View Dependent Claims (21)
