Abstract
A radiation detector includes a housing configured to contain a volume of water, the housing including an interior surface adjacent a first portion of the water having a first net charge. The radiation detector also includes a first electrode coupled to the housing within the first portion of the water, and a second electrode coupled to the housing within a second portion of the water adjacent the first portion of the water. The radiation detector further includes a current detector connected in series between the first electrode and the second electrode, the current detector configured to detect a current associated with an ionized radiation product that enters the housing.
Claims18
A radiation detector comprising:
- a housing configured to contain a volume of water, said housing comprising an interior surface adjacent a first portion of said water having a first net charge, wherein said interior surface comprises one of (i) a hydrophilic surface such that the first net charge comprises a negative charge, and (ii) a hydrophobic surface such that the first net charge comprises a positive charge;
- a first electrode coupled to said housing within said first portion of said water;
- a second electrode coupled to said housing within a second portion of said water adjacent said first portion of said water;
- and
- a current detector connected in series between said first electrode and said second electrode, said current detector configured to detect a current associated with an ionized radiation product that enters said housing.
A method for constructing a radiation detector, said method comprising:
- dispensing a volume of water into a housing configured to contain the water, wherein the housing includes an interior surface adjacent a first portion of the water, wherein said interior surface comprises one of (i) a hydrophilic surface such that the first net charge comprises a negative charge, and (ii) a hydrophobic surface such that the first net charge comprises a positive charge;
- positioning a first electrode within the first portion of the water;
- positioning a second electrode within a second portion of the water adjacent the first portion of the water;
- and
- connecting a current detector in series between the first electrode and the second electrode, wherein the current detector is configured to detect a current associated with an ionized radiation product that enters the housing.
A radiation detector comprising:
- a housing configured to contain a volume of water, said housing comprising an interior surface adjacent a first portion of said water having a first net charge, wherein said interior surface comprises one of (i) a hydrophilic surface such that the first net charge comprises a negative charge, and (ii) a hydrophobic surface such that the first net charge comprises a positive charge;
- and
- a circuit formed through said first portion of water and a second portion of water adjacent said first portion of water, said second portion of water having a second net charge with a polarity opposite the first net charge, said circuit comprising a current detector configured to detect a flow of charge from one of said first and second portions of water to the other of said first and second portions of water, the flow of charge associated with an ionized radiation product that enters said housing.
A radiation detector comprising:
- a plurality of detector elements arranged in an array, each detector element of said plurality of detector elements comprising:
- a housing configured to contain a volume of water, said housing comprising an interior surface adjacent a first portion of said water having a first net charge, wherein said interior surface comprises one of (i) a hydrophilic surface such that the first net charge comprises a negative charge, and (ii) a hydrophobic surface such that the first net charge comprises a positive charge;
- a first electrode coupled to said housing within said first portion of said water;
- a second electrode coupled to said housing within a second portion of said water adjacent said first portion of said water;
- and
- a current detector connected in series between said first electrode and said second electrode, said current detector configured to detect a current associated with an ionized radiation product that enters said housing.
