Abstract

Abstract A thermoluminescence dosimeter is integrated with a dosimeterholding member to simplify and assure its handling as well as to prevent the generation of miscellaneous luminescences, for example, a luminescence due to the heat of friction. The reliability of the thermoluminescence dosimeter is thereby greatly improved in measuring dose.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 106 words
A thermoluminescence dosimeter of an external heating type for measuring a dose comprising: an elongated glass member having a hermetically sealed hollow cylindrical end portion and an elongated opposite end portion of reduced diameter with respect to said sealed cylindrical end portion; a thermoluminescent material filling said hollow cylindrical end portion and adapted to be heated exteRnally for reading a dose, and a handling member integrally fixed to said glass member at said end opposite to said cylindrical end portion, said handling member being substantially thermally isolated from said thermoluminescent material and being adapted to be handled directly by hand and to be marked for identification.
Claim 2
Dependent Claim 106 words
A thermoluminescence dosimeter of an external heating type for measuring a dose comprising: an elongated glass member having a hermetically sealed hollow cylindrical end portion and an elongated opposite end portion of reduced diameter with respect to said sealed cylindrical end portion; a thermoluminescent material filling said hollow cylindrical end portion and adapted to be heated exteRnally for reading a dose, and a handling member integrally fixed to said glass member at said end opposite to said cylindrical end portion, said handling member being substantially thermally isolated from said thermoluminescent material and being adapted to be handled directly by hand and to be marked for identification.
Claim 3
Dependent Claim 103 words
A thermoluminescence dosimeter of an external heating type for measuring a dose comprising: a disc-shaped thermoluminescent element made of a thermoluminescent material and shaped with a resin binder and adapted to be heated externally for reading a dose; a frame member having a frame portion for holding said thermoluminescent element and a projected portion extended outwardly from said frame portion, and a handling member integrally fixed to the end of said projected portion of said frame member, said handling member being substantially thermally isolated from said thermoluminescent material and being adapted to be handled directly by hand and to be marked for identification.
Claim 4
Dependent Claim 103 words
A thermoluminescence dosimeter of an external heating type for measuring a dose comprising: a disc-shaped thermoluminescent element made of a thermoluminescent material and shaped with a resin binder and adapted to be heated externally for reading a dose; a frame member having a frame portion for holding said thermoluminescent element and a projected portion extended outwardly from said frame portion, and a handling member integrally fixed to the end of said projected portion of said frame member, said handling member being substantially thermally isolated from said thermoluminescent material and being adapted to be handled directly by hand and to be marked for identification.
Claim 5
Dependent Claim 177 words
A dosimetry system for measuring a radiation dose, comprising: an elongated glass member having a hermetically sealed hollow cylindrical end portion and an elongated opposite end portion of reduced diameter with respect to said sealed cylindrical end portion; a thermoluminescent material filling said hollow cylindrical end portion and adapted to be heated externally for reading a dose; a handling member integrally fixed to said glass member at said end opposite to said cylindrical end portion, said handling member being substantially thermally isolated from said thermoluminescent material and being adapted to be handled directly by hand and to be marked for identification; a dosimeter case having an opening therein and an internal space in communication with said opening; and a radiation shield having a predetermined number of perforations lining the walls of said internal space; said thermoluminescence dosimeter being detachably inserted into said dosimeter case such that said sealed cylindrical end portion of said glass member is disposed in said internal space in spaced relation to said shield, and said handling member being detachably secured to said opening.
Claim 6
Dependent Claim 177 words
A dosimetry system for measuring a radiation dose, comprising: an elongated glass member having a hermetically sealed hollow cylindrical end portion and an elongated opposite end portion of reduced diameter with respect to said sealed cylindrical end portion; a thermoluminescent material filling said hollow cylindrical end portion and adapted to be heated externally for reading a dose; a handling member integrally fixed to said glass member at said end opposite to said cylindrical end portion, said handling member being substantially thermally isolated from said thermoluminescent material and being adapted to be handled directly by hand and to be marked for identification; a dosimeter case having an opening therein and an internal space in communication with said opening; and a radiation shield having a predetermined number of perforations lining the walls of said internal space; said thermoluminescence dosimeter being detachably inserted into said dosimeter case such that said sealed cylindrical end portion of said glass member is disposed in said internal space in spaced relation to said shield, and said handling member being detachably secured to said opening.
