Ratios of UV, PAR and NIR components to global solar radiation measured at Botucatu site in Brazil
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
The relationships between the four radiant fluxes are analyzed based on a 4 year data archive of hourly and daily global ultraviolet (I(UV)), photosynthetically active-PAR (I(PAR)), near infrared (I(NIR)) and broadband ...
Piezo and pyroelectric radiation dosimetry
(1992-08-01)
The authors review the use of photoacoustic and pyroelectric radiation dosimeters. They compare the characteristics and results obtained with a photoacoustic radiation dosimeter (PARD) and a pyroelectric radiation dosimeter ...
Human genetic studies in areas of high natural radiation. IX. Effects on mortality, morbidity and sex ratio
(Williams & Wilkins, 1978-01-01)
Two thermal methods to measure the energy fluence of a brief exposure of diagnostic x rays
(1992-07-03)
This paper describes two simple thermal methods for measuring the energy fluence in J/cm 2 from a diagnostic x-ray exposure. Both detectors absorb essentially 100% of the radiation and give a signal that is directly ...
Gene Expression Profiles in Radiation Workers Occupationally Exposed to Ionizing Radiation
(JAPAN RADIATION RESEARCH SOC, 2009)
Ionizing radiation OR) imposes risks to human health and the environment. IR at low doses and low (lose rates has the potency to initiate carcinogenesis. Genotoxic environmental agents such as IR trigger a cascade of signal ...
Doping of polyaniline and derivatives induced by X-ray radiation
(1997-01-01)
Thin films of chemically synthesized polyaniline and poly(o-methoxyaniline) were exposed to ionizing X-ray radiation and characterized by radiation induced conductivity measurements, ultraviolet-visible spectroscopy, ...
Diurnal evolution of the hourly diffuse solar radiation incident on tilted surfaces in Southeast of Brazil
(2013)
Evaluation has been made on the monthly and annual average diurnal evolution of the hourly diffuse radiation as well as its radiometric fractions on surfaces inclined at 12.85, 22.85 and 32.85° to face North, in climate ...
Estimativa do saldo de radiacao em Jaboticabal (SP)
(1988-12-01)
This work deals with net radiation (Q*) estimates as function of solar radiation (K↓) for the Jaboticabal region in Sao Paulo State. In the same way shows a comparison between measured and Penman estimates net radiations. ...
Chicken meat submitted to gamma radiation and packed with or without oxygen
(2015-01-01)
The objective of this study was to evaluate the effects on gamma radiation levels on the physical and microbiological characteristics of chicken breast meat. A completely randomized experimental design in a 4x2x3 factorial ...
