Analytical and rheological studies of modified gel dosimeters exposed to X-ray beamsAnalytical and rheological studies of modified gel dosimeters exposed to X-ray beams
(Microchemical Journal, 2016-07)
The need to know the dose of X-rays to be applied to patients suffering diseases such as cancer requires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimeters has yielded excellent results ...
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 ...
Temperature-compensated MOS dosimeter fully integrated in a high-voltage 0.35 µm CMOS process
(Institute of Electrical and Electronics Engineers, 2020-06)
This article presents the design, fabrication, and characterization of an integrated differential dosimeter based on the mismatch of two identical field oxide MOS transistors (FOXFETs). This dosimeter was fabricated in a ...
