The purpose of this work is to briefly review the relevant anatomical and mass transport aspects of respiratory tract dosimetry that can be applied to Category 1 gases. This is carried out from the prospective of dosimetry modeling. As such, the presentation is divided into the following main ...
How May the Dosimetry of Inhaled Particles Play a Role in the Observed Mortality/Morbidity Associated with PM10?The purpose of this paper is to present a method for estimating particle doses that may be used to reconcile particle deposition doses used in in vitro toxicology studies with in ...
We will let the reader decide who, in our story, is Achilles and who is the tortoise. 2. Evolution of dosimetry in MRT and EBRT 2.1. MRT The first use of radionuclides for therapeutic purpose dates to the late 30ies, when patients suffering from chronic leukemia were treated with oral ...
Similarly, it is known that resolution modeling (RM) within the reconstruction, which attempts to decrease the PVE, can introduce artefacts in the activity distribution, depending on the method and application [14]. For these reasons, several guidelines on quantitative SPECT/CT for dosimetry ...
Demographics, dosimetry, and clinical outcomes were recorded. Univariate, relative risk, and Kaplan-Meier analyses were performed to relate dose to toxicity endpoints including retinopathy, vision decline, and cataracts. Results By the end of follow up (Median = 3.6 years, Range = 0.4 – 13.5 ...

Here we describe the Lunar Lander Neutron & Dosimetry experiment (LND) which is part of the Chang’E 4 Lander scientific payload. Its chief scientific goal is to obtain first active dosimetric measurements on the surface of the Moon. LND also provides observations of fast neutrons which are a...
Natural building stones must be analysed according to a legally defined procedure to prove that the natural radioactivity they emit is below the so-called
This study aimed to find a better dosimetric parameter in predicting of radiation-induced lung toxicity (RILT) in patients with non-small cell lung cancer (NSCLC) individually: ventilation(V), perfusion (Q) or computerized tomography (CT) based. V/Q sing
Engineering solutions were designed to fit the emission. The factory is an example of a stationary source and the automobile an example of a mobile source. Somehow, all the releases from these sources had to be connected to the air quality of a neighborhood, town, or larger area. Thus, if...
