Radon is generally the greatest source of natural radiation
exposure due to the following characteristics.
Internationally accepted limits are set for members of the public for doses that are in addition to background or natural radiation
. The limit is set at one millisievert a year.
Kuwait's representative at the event was Health Ministry natural radiation
specialist Abdulhalim Shafiq Al-Bobbo, who said that the workshop discussed the concept of nuclear security and its legislative framework.
"We think the most important single take-away point for concerned passengers is to keep an appropriate perspective: the effective radiation dose received by a passenger during screening is comparable to what that same passenger will receive in 12 seconds during the flight itself or from two minutes of natural radiation
exposure." Sources of Radiation Natural sources of radiation on the ground include terrestrial sources such as radon in the air, cosmic radiation from space, and even the decay of potassium in the human body.
Ninety-nine percent of those tested, he said, received less than 2.4 millisieverts per year, a dose equivalent to what most people around the world receive from natural radiation
in the environment.
But fresh scientific studies have just authoritatively confirmed earlier warnings that the high natural radiation
contamination levels of the ancient water deposits held by the aquifer pose a significant mass cancer risk.
The device allows students to see the miniature vapour trails created by natural radiation
, or "cosmic rays", and can help them get to grips with concepts which are not usually visible to the naked eye.
By some reason, nature has arranged that we must coexist in harmony with the natural radiation
Observations of wind patterns and natural radiation
patterns on Mars by NASA's Curiosity rover are helping scientists better understand the environment on the Red Planet's surface.
People are affected by natural radiation
in the air, soil and atmosphere and from other manmade sources of ionizing radiation.
