potassium isotopes การใช้

• All other potassium isotopes have half-lives under a day, most under a minute.
• Shales however, are naturally radioactive due to potassium isotopes in clays, and adsorbed uranium and thorium.
• Argon comes from the decay of radioactive Potassium isotopes . . . and so on . talk ) 20 : 30, 19 November 2007 ( UTC)
• 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 . If the assumed time of residence in the body is reduced by a factor of ten, for example, the estimated equivalent absorbed dose due to the banana will be reduced in the same proportion.
