Banana equivalent dose BED is an informal measurement of ionizing radiation banana man porn, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by eating one average-sized banana. Bananas contain naturally occurring radioactive isotopesparticularly potassium 40 K.

One BED is often correlated to 0. The origins of the concept are uncertain, but one early mention can be found on the RadSafe nuclear safety mailing list inwhere Gary Mansfield of the Lawrence Livermore National Laboratory mentions that he has found the "banana equivalent dose" to be "very useful in attempting to explain infinitesimal doses and corresponding infinitesimal risks to members of the public".

The banana equivalent dose is an informal measurement, so any equivalences are necessarily approximate, but it has been found useful by some as a way to inform the public about relative radiation risks.

A lethal dose of radiation is approximately 35, BED mSv. Banana man porn major natural source of radioactivity in plant tissue is potassium: This isotope decays with a half-life of about phoenix porn hub. Since a typical banana contains about half a gram of potassium, [7] it will have an activity of roughly 15 Bq.

The dose uptake from ingested material is defined as committed doseand in the case of the overall effect on the human body of the radioactive content of a banana, it will be the "committed effective dose". This is typically given as the net dose over a period of 50 years resulting from the intake of radioactive material.

In informal publications, one often sees this estimate rounded up to 0. The International Comission on Radiological Protection estimates a coefficient of 6.

Several sources point out that the "banana equivalent dose" banana man porn a flawed concept, because in fact consuming a banana does not increase the exposure to radioactive potassium. The committed dose in the human body due to bananas is not cumulative because the amount of potassium and therefore of 40 K in the human body is fairly constant due to homeostasis[14] [15] so that any excess absorbed from food is quickly compensated by the elimination of an equal amount.

It follows that the additional radiation exposure due to eating a banana lasts only for a few hours after ingestion, banana man porn. The EPA conversion factor, on the other hand, is based on the mean time needed for the isotopic mix of potassium isotopes in the body to return to the natural ratio after being disturbed by the ingestion of pure 40 K, which was assumed by EPA to be 30 days.

These amounts may be compared to the exposure due to the normal potassium content of the human body2. Other food rich in potassium and therefore in 40 K include potatoeskidney beansbanana man porn, sunflower seedsbanana man porn, and nuts.

From Banana man porn, the free encyclopedia, banana man porn. Accessed 26 December The average radiation dose to people living within 10 miles of the plant was 0. The number of atoms of 40 K in one gram of natural potassium is 40 K's mole-fraction 0. As in any exponential decaythe average lifetime is the half-life 3.

Physics in Medicine and Biology. Peeling Away the Mystery". Accessed 14 March Radiological and Nuclear Banana man porn Devices. Accessed 25 May This is because the biokinetic model for potassium used in this document represents the relatively slow removal of potassium biological half-time 30 days that is estimated to occur for typical intakes of potassium, whereas an elevated intake of potassium would result in excretion of a nearly equal mass of natural potassium, and hence of 40 K, over a short period.

It is important to recognize that the potassium content of the body is under strict homeostatic control and is not influenced by variations in environmental levels. For this reason, the dose from 40 K in the body is constant. Sequoia,p. Department of Energy archived from the original on Musa acuminataM.
