Neutron-Induced Dose Enhancement in Tantalum

IEEE Transactions on Nuclear Science, 1975
Local dose enhancement caused by neutron capture in tantalum devices has been predicted but not previously measured. An experiment is reported in which the dose due to conversion electrons and sub-MeV photons resulting from neutron capture in Ta is compared to the dose from high-energy photons. For measurements on a thin Ta foil using a silicon surface

Contrast dose for enhancement of computed tomograms of the brain

The British Journal of Radiology, 1979
This study shows that contrast enhancement of cerebral lesions can be adequately achieved with a bolus injection of 60 ml of sodium iothalamate 70%. While the infusion of a larger dose of contrast agent increases quantitatively the level of enhancement of a variety of lesions, this method of examination does not appear to provide any more useful ...

Neurotoxicity is not enhanced by increased dose intensities of cisplatin administration

European Journal of Cancer, 1995
It is uncertain whether intensive dosing schedules of cisplatin, intended to attain a higher anti-tumour efficacy, alter the severity of cisplatin-induced neuropathy. We assessed the development of neuropathy in three groups of patients treated with cisplatin in different dosing schedules. The severity of neuropathy was determined by measurement of the

Calculations of dose enhancement in device structures

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1989
Abstract Using a semi-empirical electron transport model and the solution of the one-group S > 2 transport equation for a multilayered system, we have developed a fast algorithm for calculating X-ray dose enhancement in device structures. The program MULTILAYER, written in BASIC for an IBM-PC compatible microcomputer, calculates (1) the dose ...

Enhancement of phenytoin elimination by multiple-dose activated charcoal

Annals of Emergency Medicine, 1987
The effect of multiple-dose activated charcoal on the elimination of intravenously administered phenytoin was studied. Seven normal volunteers received phenytoin sodium 15 mg/kg IV with and without activated charcoal. During the charcoal phase, a total dose of 300 g was administered in repeated doses over 48 hours with sufficient sorbitol to produce ...

Dose-Dependent Enhancement Effects of Azone on Skin Permeability

Pharmaceutical Research, 1989
In vitro permeability experiments have been combined with differential scanning calorimetry (DSC) studies in an attempt to address the dose-dependent influence of Azone on the permeability coefficients of solutes for hairless mouse stratum corneum. A spray technique was developed to deliver uniformly and quantitatively small amounts of Azone to the ...

Enhancing the radiation dose detection sensitivity of optical fibres

Applied Radiation and Isotopes, 2015
A method for improving the thermoluminescence (TL) yield of silica-based optical fibres is demonstrated. Using silica obtained from a single manufacturer, three forms of pure (undoped) fibre (capillary-, flat-, and photonic crystal fibre (PCF)) and two forms of Ge-doped fibre (capillary- and flat-fibre) were fabricated.

X-Ray Dose Enhancement, II.

1978
Abstract : A discussion of x-ray dose enhancement at material interfaces is presented including definition, problem identification and worst-case estimation, prediction techniques, and analysis of dose enhancement characteristics. Empirical, analytical, and Monte Carlo prediction techniques are discussed.

Low doses of radiation can enhance insect lifespans

Biogerontology, 2013
This paper assesses the capacity of ionizing radiation to extend the lifespans of experimental insect models based on the peer-reviewed literature. Ionizing radiation biphasically affects the lifespans of adult males and females for a broad range of insect models with high doses reducing lifespan whereas lower doses can enhance lifespan, typically in ...
