Radiation occurs from three natural sources: radioactive material in the environment such as in soil, rock, or building materials; cosmic rays; and substances in the human body, such as radioactive potassium in bones and radioactive carbon in tissues. These natural sources account for an exposure...

A clear conceptualization of the sources of radiation is necessary for an adequate understanding of the relative risks from ionizing radiation. There are two major sources of such exposure: natural background and the medical uses of ionizing radiation. The latter includes almost exclusively the ...

Natural Radiation Sources Fabricated from Low-Sodium Salt and Evaluation of Their Practical Usability as Educational Material Low-sodium salt is produced to prevent over-consumption of salt by substituting potassium chloride (KCl) for 30 or 50 wt% of sodium chloride (NaCl) in the ... Takao,...
infectiousenteritis, radiation-induced enteritis, and noxious mucosal irritation (e.g.,sennalaxatives). Recent advances in the basic science of brain-to-gut and immune cells-to-ENS signaling have introduced fresh insight into mechanisms underlying the effects of psychological stress on the intestinal ...
“Methods”). Using alternative designs, we can also quantify the potential threat of additional sources of bias from unobserved, time-varying plot-level confounders and from reverse causality (by bias from reverse causality, we mean bias that could arise when a causal effect also runs from ...
People working with ionising radiation are receiving radiation coming from artificial and natural sources. In Spain, as in many other countries, there is a serious control by the national authorities, Spanish Nuclear Safety Council, of the dose the workers receive from artificial sources. However, ...

The spectra of light sources used for artificial lighting are well-known and can be easily measured in the laboratory. But what does the night sky look like in the darkest (most natural) areas? The night sky radiance is made up of several components. A continuum of radiation is spectrally ...
