The sources of radiation in the Universe are many, but can be grouped for simplicity in natural and man-made. Natural radiation is radiation whose source can be traced to be of either terrestrial, solar or astronomical nature and as such is typically found in our everyday life. This chapter...
Natural sources of radiation exposure and the teaching of radioecology We have developed an experimental activity that introduces concepts of the natural ionizing radiation and its interaction with our contemporary environment... RM Anjos,R Veiga,C Carvalho,... - 《Physics Education》 被引量: 24发...
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...
Sources of this include the medical use of radioactive materials, fallout and contamination from nuclear bomb tests, discharges from the nuclear industry, and the storage and dumping of radioactive waste. While artificial radiation accounts for a small proportion of the total, its effects can be ...

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, ...
Natural radionuclides of special concern related to radiation protection are radon (mostly 222Rn) and its decay products, as they are the most important sources of radiation exposure to the public, contributing about half of the total effective dose equivalent received from natural and anthropogenic ...
of stress in biological conservation. This approach considers the stress response of organisms as an evolved trait with an adaptive value and provides a yardstick (Darwinian fitness) to measure the consequences of anthropogenic and natural sources of stress that is of direct relevance to conservation....
LPG is a by-product from two sources:natural gas processingand crude oil refining. When natural gas is produced, it contains methane and other light hydrocarbons that are separated in a gas-processing plant. Thenatural gas liquidcomponents recovered during processing include ethane, propane, and bu...
