Piezo and pyroelectric radiation dosimetry
(1992-08-01)
The authors review the use of photoacoustic and pyroelectric radiation dosimeters. They compare the characteristics and results obtained with a photoacoustic radiation dosimeter (PARD) and a pyroelectric radiation dosimeter ...
Field Oxide n-channel MOS Dosimeters Fabricated in CMOS Processes
(Institute of Electrical and Electronics Engineers, 2013-12)
This paper presents a new technique to build MOS dosimeters using unmodified standard CMOS processes. The devices are n-channel MOS transistors built with the regular Field Oxide as a thick radiation-sensitive gate. The ...
Switched Bias Differential MOSFET Dosimeter
(Institute of Electrical and Electronics Engineers, 2014-06)
This paper presents a differential MOSFET sensor reading technique based on the bias controlled cycled measurement. The circuit was implemented, and tested with gamma radiation from a 60-cobalt source. Temperature rejection ...
Poly [1,1'-bis(ethynyl)-4,4'-biphenyl(bis-tributylphosphine)Pt(II)] solutions used as low dose ionizing radiation dosimeter
(2013-06-17)
In this work, the effect of gamma radiation on the optical properties of polymetallayne poly[1,1'-bis(ethynyl)-4,4'-biphenyl(bis-tributylphosphine)Pt(II) ] (Pt-DEBP) in chloroform solution is studied. The samples were ...
CMOS differential and amplified dosimeter with field oxide N-channel MOSFETs
(Institute of Electrical and Electronics Engineers, 2014-12)
We propose the use of a CMOS differential circuit with inherent amplification to enhance the performance of n-channel field oxide MOSFETs as ionizing radiation dosimeters. These new dosimeters are aimed to be used in low ...
Polymer gel dosimeter based on itaconic acid
(Elsevier, 2015-07)
A new polymeric dosimeter based on itaconic acid and N, N’-methylenebisacrylamide was studied. The preparation method, compositions of monomer and crosslinking agent and the presence of oxygen in the dosimetric system were ...
A PHOTOACOUSTICAL RADIATION DOSIMETER
(Amer Inst PhysicsWoodbury, 1984)
Floating Gate sensor for in-vivo dosimetry in radiation therapies: design and first characterization
(IOP Publishing, 2017-03)
A floating gate dosimeter was designed and fabricated in a standard CMOS technology. The design guides and characterization are presented. The characterization included the controlled charging by tunneling of the floating ...
Thermoluminescence of aluminophosphate glasses in the metaphosphate composition
(Elsevier B.V., 2006-05-01)
Potassium aluminum phosphate (KAP) glasses in the system xKPO(3)-(100-x)AI(PO3)3 with x = 10, 30 and 50 mol% were prepared in the metaphosphate composition. The glasses were doped with MnO2 and their thermoluminescent (TL) ...
Analytical and rheological studies of modified gel dosimeters exposed to X-ray beams
(Elsevier Science, 2016-07)
The need to know the dose of X-rays to be applied to patients suffering diseases such as cancerrequires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimetershas yielded excellent results ...
