Radioactive Isotopes Are Useful in Biological Studies Because

It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air and forms a dull coating when oxidizedThe element normally exhibits six allotropes and four oxidation statesIt reacts with carbon halogens nitrogen silicon and hydrogenWhen exposed to moist air it. Oxygen-15 or 15O is an isotope of oxygen having a half life of about two minutes.

Tritium has many uses including self-powered lighting as a component in nuclear weapons as a radioactive label in chemistry lab work as a tracer for biological and environmental studies and for.

. Nitrogen-13 or 13N is an isotope of nitrogen with a half life of approximately ten minutes. A functional neuroimaging technique that uses radioactive isotopes to quantify regional cerebral blood flow glucose metabolism or receptor occupancy. Thorium is silvery and tarnishes black when it is exposed to air forming thorium dioxide.

Carbon-11 or 11C is a radioactive isotope of carbon with a half-life in the order of twenty minutes. Because beta particles are a form of ionizing radiation the expected health effect from internal exposure to tritium would be an elevated risk of developing cancer. Single nucleotide polymorphism SNP A variation in a DNA sequence in which a single nucleotide A C G or T at a specific locus differs between members of the same biological species or between paired chromosomes of an.

All the used isotopes are radioactive with a rapid time of decaying by positron emission. It is moderately soft and malleable and has a high melting pointThorium is an electropositive actinide whose chemistry is dominated by the 4 oxidation state. Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94.

Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90.
