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 presents an account of only a handful of the most common natural radiation sources: the cosmic background ...
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...

The main source comes from natural sources in space, rocks, soil water and even the human body itself. This is called background radiation and levels vary from place to place, though the average dose is fairly constant. The radiation which is of most concern is artificial radiation which ...
Abstract The radiation dose to the population of Israel due to exposure to natural sources of ionizing radiation was assessed. The main contributor to the dose is radon that accounts for 60% of the exposure to natural sources. The dose due to radon inhalation was assessed by combining the resu...

safety standards for the radiation protection of the public and the environment (i.e., any public exposure from normal operations must be below 1 mSv per year237). However, it should be noted that there are orders of magnitude differences in the activities released and the type of radionucl...
Two classes of experiments are possible with satellite-carried instruments: (1) To measure natural phenomena; (2) To create artificial effects under controlled conditions.doi:10.1007/978-94-010-3553-8_41N. C. ChristofilosSpringer Netherlands
