12 Feb 2006, 10:04 AM  | transuranic and commercial You can hide this advertisement by registering. hi ppl,what exactly do we write for this dotpoint describe how commerical radioisotopes r produced? i wrote about cyclotrons and nuclear reactors and gave some examples but aren;t transuranic elements produced in the same way i mean transuranci elements are also produced by nuclear reactors and accelerators i am confused. help!!! plzzz

18 Jul 2006, 4:26 PM | Hi, In general, yes! radioisotopes and transuranic elemens are produced using similar techological equipment, cyclotrons... nuclear reactions. For more information on the production of these go to http://www.chemistrycoach.com.au/resources.htm which contains a list of GOOD assignments on this part of the syllabus .. |

17 May 2009, 2:11 PM | the two dp are awfully similar... sth along the lines of: "how are commercial radioisotpes produced" "how are transuranic elements produced" both maybe from linear accelerator, cyclotron, nulear reactor... know 1 example of each will aid u too...

19 Nov 2009, 8:54 PM | You get a bit more specific with commercial radioisotopes, you gotta talk about not just the original element and how its bomarded, but any decay processes it has too go through (or may go through) to get desired product (ie. Tc-99m), some don't require that (like Americium)- but theres' a distinct difference but if you say transuranic elements produced its alot simpler, you just say how one is produced (ie. bombardment of neutrons) and thats it

19 Nov 2009, 8:54 PM | Yeh I was reading it on CSU, Transuranic is basically stepping up the weight/atomic numbers, and commercial is usually fission into smaller elements, or decaying ... Its very general what I'm saying, go to csu for the specificly what I'm talking about
