Radioisotopes - copper-64 (1 Viewer)

[Maddkent]

doing a chemistry assignment, need to kno the decay equation for copper-64, help much appreciated

 

[Maddkent]

doesnt matter anymore, couldnt find anything on copper-64 so i used technetium-99m instead, could find heaps on it

 

[Pwnage101]

yeh, tc-99m is much better to use because there is a lot of info on it

Used in imaging (positron emission tomography, and in detecting Wilson's disease) and radiotherapy, Cu-64 is produced through radioactive decay of zinc-68 (created by enriching zinc with fast electrons).

[You know the equation here, dude. I don't have a periodic table handy, and I don't know the atomic numbers of Copper and Zinc. (I do, however, remember Copper's atomic mass as being 63.55 amu's.)]

The irradiated zinc target is dissolved in H₂O, and the pH of the solution is adjusted to about 6.
Radioactive copper atoms are then extracted with a 1% solution of resacetophenone oxime in cyclohexanone. (Zinc is not extracted under these conditions.)

Radioactive copper is back-extracted by shaking the organic phase with dilute mineral acid, and voila!


My advice, if you don't have to do Cu-64, is to do Tc-99m.
1. It's less pretentious regurgitating the production and uses in relation to properties.
2. It's easy; why make life harder for yourself?
3. I dunno, I'm making this shit up as I go.
