Desenvolvimento de protocolos de dosimetria interna empregando o código MCNPx e fantomas voxelizados de referência da ICRP 110

Brazilian Journal of Radiation Sciences, 2017
The objective of this work was to develop and validate Internal Dosimetry Protocols (IDP) using the ICRP 110 reference voxelized phantoms (RCP_AF and RCP_AM). The reference phantoms were implemented to run on MCNPx.

Overview of the sensitivity of Ge- and Al-doped silicon dioxide optical fibres to ionizing radiation [PDF]

, 2012
This paper reviews the thermoluminescence sensitivity of Ge- and Al- doped SiO2 optical fibre subjected to various ionizing radiations. It is found that the Ge- doped SiO2 optical fiber has the thermoluminescence response superior to Al-doped SiO2 ...

Whole breast and regional nodal irradiation in prone versus supine position in left sided breast cancer [PDF]

, 2017
Background: Prone whole breast irradiation (WBI) leads to reduced heart and lung doses in breast cancer patients receiving adjuvant radiotherapy. In this feasibility trial, we investigated the prone position for whole breast + lymph node irradiation (WB +

Calibration of gamma cameras for the Evaluation of Accidental Intakes of high-energy photon emitting Radionuclides by humans based on Urine Samples

Brazilian Journal of Radiation Sciences, 2018
The prompt response to emergency situations involving suspicion of intakes of radionuclides requires the use of simple and rapid methods of internal monitoring of the exposed individuals.

Individual monitoring for internal exposures in Europe: Conclusions of an EURADOS action [PDF]

, 2017
Once the EC Directive 96/29 has been implemented into national regulation across Europe, the coordination of dosimetry laboratories for the monitoring of occupational exposures becomes the principal aim to achieve.

Visualizing and Quantifying Impact with Mechanochromic Sensing Paints Based on Self‐Assembled Polydiacetylene‐Silk Core‐Shell Vesicles

Advanced Science, EarlyView.
Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

Monitoring internal contamination from OEW of an 18F-FDG production plant: WBC or head counting setup?

Brazilian Journal of Radiation Sciences, 2019
The production 18F-FDG for positron emission tomography (PET) has consistently increased over the past two decades. The risk of internal contamination at 18F-FDG production facilities exists.

Evaluation of the applicability of the inductively coupled plasma mass spectrometry method for special individual dosimetry monitoring

Радиационная гигиена, 2023
In the condition of modern radiation hazardous production, higher levels of personnel internal exposure are mainly due to the intake of radionuclides in situations caused by faulty equipment or wrong actions of personnel which can or do result in the ...

Informing Selection of Nanomaterial Concentrations for ToxCast In Vitro Testing based on Occupational Exposure Potential [PDF]

, 2011
Background: Little justification is generally provided for selection of in vitro assay testing concentrations for engineered nanomaterials (ENMs). Selection of concentration levels for hazard evaluation based on real-world exposure scenarios is desirable.
