Another K39 paper

[Muckerheide <muckerheide@attbi.com>]

Friends, 



Please note this abstract also showing that removing K-40 from natural

potassium and "protecting" animals from background radiation causes

detrimental effects.



Do you have access to a Russian translator? :-)

Kuzin, A. M., V. P. Krymskaya, et al. (1994). "The significance of the

radioactive isotope potassium-40 for the normal development of the animal

organism [in Russian]." Radiats Biol Radioecol 34(1): 73-8.



    21-day-old rats subjected to nourishing by KCl (20-30 mg per day)

without radioactive isotope 40K. Besides the decrease of 40K content in

animal tissue (30-50%) a reducing of body weight was obtained. In the second

set of experiments in the lead (9 cm thick) chamber with low (20 times)

background radiation the trustworthy decrease of young mouse development was

observed under the simultaneous reducing other components of background

radiation (radon, products of its disintegration, gamma, beta radiation,

cosmic radiation). Possible mechanisms of necessity of 40K natural

concentration for the normal development of the animal organism are

discussed.
