A comparison of personal dose equivalent measurements made by personal dosemeters

Radiation Physics and Chemistry, 2014
Abstract Individual monitoring services for external radiation were tested in the Czech Republic. The results of the tests show that they are dosimetry systems authorized and regularly tested in the Czech Republic having outliers for low energy region and angle of 50 degree and greater.

A correlation study of eye lens dose and personal dose equivalent for interventional cardiologists

Radiation Protection Dosimetry, 2013
This paper presents the dosimetry part of the European ELDO project, funded by the DoReMi Network of Excellence, in which a method was developed to estimate cumulative eye lens doses for past practices based on personal dose equivalent values, H(p)(10), measured above the lead apron at several positions at the collar, chest and waist levels ...

Thermoluminescence Dosemeter for Personal Dose Equivalent Assessment

Radiation Protection Dosimetry, 1995
The possibility was investigated of utilising a Brazilian thermoluminescence individual dosemeter, usually calibrated in terms of photon dose equivalent, for the assessment of the personal dose equivalent, Hp p (d), at depths of 0.07 and 10 mm. The dosemeter uses four CaSO 4 :Dy thermoluminescent detectors, between different filters, as the sensitive ...

Calibration factor for estimating personal dose equivalent with imaging plates

Radiation Measurements, 2005
A personal imaging plate (IP) dosimeter is in the process of being developed for neutron fields using the BaFBr:Eu$^{2+}$ phosphor. A configuration incorporating a polyethylene radiator placed before the IP detector is used to produce protons via (n,p) elastic scattering.

Determination of Personal Dose Equivalents in Accelerator Radiation Fields

Radiation Protection Dosimetry, 2001
Values for the dose equivalent are required for radiation protection purposes, but determination of such values can be quite difficult for high energy radiations. The accurate determination of personal dose equivalents in accelerator radiation fields requires the propel use of appropriate radiological quantities and units, knowledge of the dose ...

Conversion coefficients from air kerma to personal dose equivalent in mammography

Radiation Physics and Chemistry, 2010
Abstract In this work, the scattered X-ray beams produced by a mammography unit with a Mo/Mo, Mo/Rh and W/Rh anode/filter combinations were applied in the evaluation of the H p ( 10 , 0 ∘ ) and mean conversion coefficients from air kerma to the personal dose equivalent ( C ¯ H p ( 10 , 0 ∘ )

Determination of ambient and personal dose equivalent for personnel and cargo security screening

Radiation Protection Dosimetry, 2006
In the past few years, imaging technology using ionising radiation has been gaining in importance for the screening of goods and persons for security reasons and in order to detect contraband. For radiation protection purposes it is extremely important to know that dose persons are exposed to when passing through a personnel scanner or, as a stowaway ...

THE RESPONSE OF THE PHE NEUTRON PERSONAL DOSEMETER IN TERMS OF THE PROPOSED ICRU PERSONAL DOSE EQUIVALENT

Radiation Protection Dosimetry, 2018
The ICRU is considering amending the definition of the operational quantity for personnel monitoring. The present work investigates the impact of the proposed change on the PHE neutron personal dosemeter, which utilizes electrochemically etched PADC and is currently optimized in terms of Hp(10). The energy-dependent dose response characteristics of the

Personal Dose Equivalent For Photons and Its Variation With Dosimeter Position

Health Physics, 1999
This work presents conversion coefficients per air kerma free-in-air for the personal dose equivalent, Hp(10), calculated according to its definition by the International Commission on Radiation Units and Measurements as a quantity in the human body. The values were calculated using Monte Carlo methods for various dosimeter positions in the trunk of a ...
