Underestimation of risk due to exposure misclassification.
Exposure misclassification constitutes a major obstacle when developing dose-response relationships for risk assessment. A non-differentional error results in underestimation of the risk. If the degree of misclassification is known, adjustment may be achieved by sensitivity analysis. The purpose of this study was to examine the full magnitude of measurement error in determining the prenatal exp...
متن کاملDose profiles in ECAL crystals for various irradiation conditions
Simulated dose profiles in various irradiation and beam test conditions are compared to the expected dose profiles in the ECAL crystals at LHC. Simple front or side irradiations with photons give too steep or too flat dose profiles, respectively. Thus, if dose maxima are fitted to agree, front irradiation underestimate the average dose whereas side irradiations tend to overestimate. Different p...
متن کاملENHANCEMENT OF DIFFUSION DUE TO IRRADIATION 527 Enhancement of Diffusion Due to Irradiation
It is shown that in a-copper-aluminium alloys interstitials are able to change sites with the copper and aluminium atoms by diffusion. The activation energy for migration of interstitials could be determined to be 0.82 eV. In a well annealed specimen the interstitials and vacancies annihilate nearly exclusively by pair recombination. The production rate of free interstitials is found to be slig...
متن کاملAdaptive changes of redox status in rat brain tissues due to decimeter microwave irradiation
Electromagnetic waves affect living organisms and it is of great interest for wide interaction of new sources with a diversity of frequencies and powers to life of people. In the last few years, many authors have proposed that the biological effect of electromagnetic fields in both the high-frequency and low-frequency ranges are connected with oxidative processes in tissues. Studying the change...
