Investigation of Natural Effective Gamma Dose Rates case study: Ardabil Province in Iran [PDF]

Gamma rays pose enough energy to form charged particles and adversely affect human health. Since, the external exposure of human beings to natural environmental gamma radiation normally exceeds that from all man-made sources combined, natural background ...

Background Radiation

, 1993
We present a short overview on the extragalactic background radiation from radio to X-rays, with an eye to the relation to galaxy formation and emphasizing on astrophysical backgrounds (as opposed to cosmological). As the radio background, the wealth of data on source counts make possible reliable estimations of the contribution from extragalactic ...

Spectrum of the microwave background radiation [PDF]

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1982
Abstract A review is given of the present status of measurements of the spectrum of the microwave background. Factors that limit experimental accuracy are discussed with particular reference to high-frequency measurements. A selection of the available measurements yields a data set that is reasonably consistent with the black-body ...

Dominant Spectra of Background Radiation in an SF_6 Post-Arc Channel [PDF]

, 1997
Composition of background spectra radiated from a SF_6 post-arc channel after current zero was investigated. The radiation intensity of the background spectra at a wavelength of 455 nm around current zero was measured.

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Background Radiation Measurements at High Power Research Reactors [PDF]

, 2015
Research reactors host a wide range of activities that make use of the intense neutron fluxes generated at these facilities. Recent interest in performing measurements with relatively low event rates, e.g.

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Design and Analysis of a Moon-Based Earth-Radiation Measurement System

Remote Sensing
This research project envisions using a lunar observation platform to measure the full-wave (0.2~100 μm) and shortwave (0.2~4.3 μm) radiation of the Earth, achieving an accurate estimation of the overall radiation budget of the Earth.

The fallacy of comparing diagnostic radiation with background radiation; and the need to learn from past mistakes

South African Journal of Radiology, 2010
The subject of radiation exposure for diagnostic purposes is currently a ‘hot’ topic, and it is appropriate that the debate around this issue is given exposure in the pages of the SAJR.
