Air kerma to H-P(3) conversion coefficients for IEC 61267 RQR X-RAY radiation qualities: application to dose monitoring of the lens of the eye in medical diagnostics [PDF]

open access: yes, 2016
Recent studies highlight the fact that the new eye lens dose limit can be exceeded in interventional radiology procedures and that eye lens monitoring could be required for these workers.

Personal dose-equivalent conversion coefficients for 1252 radionuclides [PDF]

open access: yesRadiation Protection Dosimetry, 2014
Dose conversion coefficients for radionuclides are useful for routine calculations in radiation protection in industry, medicine and research. They give a simple and often sufficient estimate of dose rates during production, handling and storage of radionuclide sources, based solely on the source's activity.

Radiation exposure in nuclear medicine: real-time measurement

open access: yesBrazilian Archives of Biology and Technology, 2002
French regulations have introduced the use of electronic dosimeters for personal monitoring of workers. In order to evaluate the exposure from diagnostic procedures to nuclear medicine staff, individual whole-body doses were measured daily with ...

Correcting the calibration curve of TLD-600 dosimeters after irradiation without phantom by thermal neutrons of Isfahan MNSR [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2023
It is shown recently that the thermal neutron field of Isfahan MNSR with stable flux and dose equivalent rate can be used as a calibration field in dosimetry. The fundamental limit of this field is not the feasibility of using phantom for the irradiation

TISSUE EQUIVALENT PERSONAL X-RAY DOSIMETER [PDF]

open access: yesBasrah Journal of Surgery, 2004
Absorbed dose from X-ray field of scattered stray radiation was monitored at presumably safety position. Lyoluminescence enhanced sensitivity in organic solid techniques were used to estimate the environmental and personal dosimeter based on tissue ...

Calculation of X-ray spectra characteristics and kerma to personal dose equivalent Hp(10) conversion coefficients: Experimental approach and Monte Carlo modeling

open access: yesNuclear Engineering and Technology, 2022
This work aims to establish some X-ray qualities recommended by the International Standard Organization (ISO) using the half-value layer (HVL) and Hp(10) dosimetry approaches.

The neutron dose equivalent around high energy medical electron linear accelerators [PDF]

open access: yesNuclear Technology and Radiation Protection, 2014
The measurement of neutron dose equivalent was made in four dual energy linear accelerator rooms. Two of the rooms were reconstructed after decommissioning of 60Co units, so the main limitation was the space. The measurements were performed by a

Comparison of different PADC materials for neutron dosimetry [PDF]

open access: yes, 2017
Investigations on track density and track size distributions of different PADC (poly allyl diglycol carbonate) materials have been performed. The PADC used for the tests has been produced by Thermo Electron (USA), Track Analysis System Limited (UK ...
