Definitions
- the invention relates to a dosimeter probe according to the preamble of claim 1, as is known from G 8510060.9.
- the object of the invention is to provide a dosimeter probe of the e. G. To provide type with light-tight encapsulation of the detector.
- the developed dosimeter probe largely meets the above requirements.
- LiF: Mg, Ti (TLD-100) is used as the detector material, which is tightly pressed into the dosimeter holder.
- the holder consists of a skin-friendly plastic (polyamide) and carries a smudge-proof, machine and clear Writable identification number.
- the dosimeter probe is waterproof, disinfectable, cold sterilizable and mechanically stable.
- the probe is designed as an open finger ring with an infinitely adjustable, self-locking closure and can also be worn on other parts of the body (forehead, arm, etc.) using additional straps. Compared to conventional systems, it is characterized by its small size, light weight and infinitely adaptable to any finger thickness. Especially in interventional and surgical radiology, the flat design makes it possible to wear the ring under the surgical glove without restricting finger mobility.
- the dosimeter probe is suitable for use in the photon equivalent dose measuring range 1 mSv ⁇ H x ⁇ 10 Sv in the energy range 15 keV ⁇ E ⁇ 1.3 MeV with radiation directions of 45 ° and fulfills the requirements for partial body dosimeters according to DIN 6816, PTB-A 23.2.1. and Section 2, Paragraph 3 Clause 4 of the Verification Act.
- FIG. 1 shows a side view
- FIG. 2 shows a top view
- FIG. 3 shows a section of the dosimeter probe.
- Fig. 1 shows the housing 1 made of polyamide with the legs 2, 3 in a side view.
- the sawtooth-shaped corrugations on the top and bottom of leg 2 and on the bottom of leg 3 are not shown here.
- At the free end of the leg 3 there is an eyelet 8 for closing the two legs 2, 3.
- the eyelet contains a sawtooth-shaped corrugation and a pawl, also not shown here.
- the corrugation on the underside of leg 3 and the corrugation on the top of leg 2 interlock. Ribbing and pawl on the eyelet 8 engage in the closed state of the legs 2, 3 in the ribbing on the underside of the leg 2.
- FIG. 2 shows the top view of the dosimeter probe.
- An abrasion-resistant exemplary marking 9 is shown on the legs 2, 3.
- the eyelet 8 at the end of the leg 3 shows the corrugation and the pawl.
- the sawtooth-shaped corrugation is indicated on leg 2.
- the cover 4 in which the detector 5 is mounted, is pressed tightly and positively into the housing 1 with the indicated legs 2, 3.
- the recess in the housing 1 is cylindrical and a blind hole is arranged in the center of this hollow cylinder.
- the bottom of the blind hole should not be thicker than 0.3 mm, which makes it possible to measure low-energy radiation.
- the lower opening of the hollow cylinder is narrowed by a ring 6 with a rectangular profile. This ring 6 ensures a tight fit of the lid.
- the cover 4 is a circular disk with a center ring attached to accommodate the thermoluminescence detector 5.
- the upward-facing surface of the circular disk and the end face and the outer wall of the circular ring form an additional seal in cooperation with the corresponding housing inner surfaces.
- the circular disc of the cover 4 has a chamfer 7 on the top, which serves as a centering aid for fitting the cover 4 into the housing 1.
- a particularly suitable material for housing 1 with legs 2, 3 and for cover 4 is polyamide.
- Other hydrophobic materials such as Teflon are also possible.
