Selenium isotopes (Se)

Selenium isotopes are used in medical, industrial and research applications. Stable selenium isotopes can be enriched or depleted by Urenco Stable Isotopes to any concentration, and supplied in various chemical forms.

Naturally occurring selenium has six stable isotopes.

Application of Selenium isotopes

Selenium 74 (Se 74)

Se-74 is used in the Non-Destructive Testing (NDT) industry in gamma cameras. Se-74 is the stable precursor of Se-75 and these sources have a relative soft gamma spectrum compared to for instance Ir-192 sources.

Selenium 76 (Se 76)

Se-76 can be used for the production of the medical isotopes Br-75 and Br-76.

Selenium 77 (Se 77)

Se-77 is used for the production of the therapeutic radioisotope Br-77.

Selenium 78 (Se 78)

Se-78 is used for the production of the therapeutic radioisotope Br-77.

Selenium 80 (Se 80)

Se-80 is used for the production of the medical radioisotope Br-80m.

Selenium 82 (Se 82)

Se-82 exhibits so-called double Beta decay and it is used in neutrinoless double Beta decay research.
