Isotopes of rhenium

Isotope data
rhenium symbol icon

Both Rhenium isotopes are used for medical purposes. Re-185 is used for the production of Re-186 which is used for bone pain palliation. 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. Rhenium isotopes can be obtained from Trace Sciences International.

Naturally occurring isotopes

This table shows information about naturally occuring isotopes, their atomic masses, their natural abundances, their nuclear spins, and their magnetic moments. Further data for radioisotopes (radioactive isotopes) of rhenium are listed (including any which occur naturally) below.
Isotope Atomic mass (ma/u) Natural abundance (atom %) Nuclear spin (I) Magnetic moment (μ/μN)
185Re 184.952951 (3) 37.40 (2) 5/2 3.1871
187Re 186.955744 (3) 62.60 (2) 5/2 3.2197

Isotopic abundances of Re
In the above picture, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer. This is not to be confused with the relative percentage isotope abundances which total 100% for all the naturally occurring isotopes.

Radiosotope data

Further data for naturally occuring isotopes of rhenium are listed above. This table gives information about some radiosotopes of rhenium, their masses, their half-lives, their modes of decay, their nuclear spins, and their nuclear magnetic moments.

Sheffield ChemPuter isotope pattern calculator

You can use WebElements to calculate an isotope pattern for an arbitrary chemical formula:

Edit this formula :

Note the following when entering your formula:

  • Correctly nested brackets [{()}] are OK
  • 'Pseudoelements' such as Me, Ph, Cp, and many others are OK
  • Compound names and element names such as 'water' or 'manganese' are not OK
  • Experiment with your formula to see what is possible
