Chapter 6  The Genetic Material. The Basic Requirements for Genetic Material (i.e., the material that determines the inherited characteristics of a functional organism): 1  It must be stable.  It must be capable of being expressed when needed.
- In the manufacture of metal or alloys. Toxicology : Zirconium compounds are generally considered to be of low toxicity. Skin : Granulomata have been produced by repeated topical applications of zirconium salts to human skin.
There are also three stable isotopes of zirconium also found in nature, which account for 79.82% of the total amount.   Yes, zirconium is radioactive (two natural isotopes):   Zr 94: half life 1,1.1017 years, double beta decay to Mo 94   Zr 96: half life 2,0.1019 years, double beta decay to Mo 94.
