Dear Agnieszka

Alpha decays are not included in the current FLUKA release. Sorry, if I wasn’t clear..

See for example older posts on this subject

Cheers

Dear Stefan,

Can You please advise how to activate alpha decays in that case?

Best regards,
Agnieszka

Dear Agnieszka

Alpha decays are not simulated and, thus, neither is the energy deposition by the alphas

Cheers
Stefan

Dear Fluka Experts,

I am trying to run simple experiment with usage of four radioisotpes: Cs137, Co60, Ra226 and Am241. I am using RADDECAY card and isotope option as a beam. My target is air-filled cylinder and I am using USRBIN card with ENERGY option set up as a particle to score (I want to score deposited energy in cylinder).

My assumption was that for all isotopes I will get quite similar results of energy deposited in cylinder, however this is not what the simulation has shown. For Co60 and Cs137 I got similar results however for Am241 and Ra226 results of the simulations differ a lot.

Can You please advise what might be wrong with my input file? Probably I am missing some significant processes that take place during the simulation or I do not understand how energy deposition is scored with USRBIN. For each simulation I am setting up HI-PROPE card with adequate mass and atomic number.

Best regards,
Agnieszka
