THE COSMIC MICROWAVE BACKGROUND RADIATION* [PDF]
Because angular anisotropies and spectral distortions of the cosmic microwave background radiation are judged to be inevitable at some level, in a realistic cosmological model, the evidence for spectral distortions and its theoretical implications are described.

Background Radiation Exposure in Transylvania, Romania: Environmental and Seasonal Influences
Background: Environmental ionizing radiation plays a major role in human radiation exposure. Natural background radiation originates from the Earth’s crust and outer space.

The cosmic microwave background radiation
We summarize the theoretical and observational status of the study of the Cosmic Microwave Background radiation. Its thermodynamic spectrum is a robust prediction of the Hot Big Bang cosmology and has been confirmed observationally. There are now 76 observations of Cosmic Microwave Background anisotropy, which we present in a table with references.

Electromagnetic Wave Collapse in a Radiation Background
The nonlinear interaction, due to quantum electrodynamical (QED) effects, between an electromagnetic pulse and a radiation background is investigated, by combining the methods of radiation hydrodynamics with the QED theory for photon-photon scattering.

Introduction: Gamma ray radiation can cause ionization and harmful effects on human health due to its high levels of energy. However, contrary to popular belief, natural sources of gamma radiation are far greater in number than artificial sources.

Fast Simulation Study of Muon Absorption Radiography Based on Energy Loss Calculation
Using natural cosmic ray muon as radiation source, muon absorption radiography can realize nondestructive detection of large-scale geological objects. Simulation analysis is an important step in the application of muon absorption radiography.

Quantum limitations of distant radiating objects detection
Weak electromagnetic signals from sufficiently distant sources reveal quantum properties. The latter ones result that detection of the sources becomes probabilistic.

Comparative study between radiation exposure in common urological procedures
Background Fluoroscopy has become essential to urological surgery since advancement of endourology. Fluoroscopy use has increased, placing urologists as well as staff members at risk for occupational radiation exposure and related dangers.

Entropy-Based Characterization of Internet Background Radiation
Network security requires real-time monitoring of network traffic in order to detect new and unexpected attacks. Attack detection methods based on deep packet inspection are time consuming and costly, due to their high computational demands.
