transuranic elements and radio isotopes (1 Viewer)

[xeriphic]

okai radioisotopes can be created in both nuclear reactor and accelerator

target nuclei bombarded with neutrons in reactor and small nucleus is accelerated to create with the target nuclei in acceleration, either these are ways to create radioisotopes

what my question is asking is does that the same for transuranic elements, if not what conditions does it require thanks

 

[Paroissien]

Yep it does, at least as far as we are concerned with it

 

[smallcattle]

basically the same procedures, it all depends on the conditions such as the atomic number of the element, the size of the bombarding material eg alpha or beta, the speed of the bombarding material, etc

 

[xeriphic]

hmm I see, thanks both

I thought we only have to know neutron bombardment in a nuclear reactor?

 

[Paroissien]

Sadly you thought wrong. You also have to know about their production in particle accelerators such as cyclotrons. It's not difficult though

 

[xeriphic]

lol in the syllabus it was one after the other

... the production of transuranic elements
... the production of radioisotopes

 

[Paroissien]

I guess he just assumed neutron bombardment would be enough for both, and who knows, that could turn out to be the case although I doubt it

 

[Shards]

how much detail do you need to go into?

 

[Paroissien]

Not that much, just make sure you have some equations that demonstrate formation through neutron bombardment and particle acceleration (just uses alpha particles)
Bombardment: Mo-98 goes to Tc-99m and U-238 goes to Np-239
Particle acceleration: N-14 goes to O-17 through alpha barticle bombardment. Gives off a proton.

Argh! Stupid tutor! So the particle accelerator is used for production of transuranic elements or radioisotopes? Or both?

Thanks BTW

 

[Paroissien]

Can be used for both. What did your tutor say?

 

[KungPow]

My tutor just said you only need to know about neutron bombardment.

 

[Paroissien]

Well for 2 mark questions you would, but there is a chance of 4+ mark questions, and then you would most likely have to refer to particle acceleration
