Isotoperna upptäcktes först för omkring hundra år sedan, men 1946 kom en amerikansk fysiker underfund med att den radioaktiva kolisotopen, kol-14, kunde användas till datering.

It is both naturally occurring and produced by fission. Osmium 187 Metal is one of over 250 stable metallic isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications.

Every chemical element has one or more isotopes. An atom is first identified and labeled according to the number of protons in its nucleus.

adshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A W-187 is a radioactive isotope that has a half-life of 1 day. Suppose you start with a 100-mg sample. What is the equation: y=100(1/2)^x (x- represents days) How would I find how long it would take for the amount of w-187 to decay to 5% of its initial amount? iZotope develops award-winning audio software and plug-ins for mixing, mastering, restoration, and more. Re-187 can be used for the production of Re-188 which is used for cancer therapy and restenosis, though most Re-188 is produced via W-186.
