[Gate-users] energy histogram for I-124 and Co-58

[DWORAK Dimitri]

Hi

To do a source of I124 you can use the command line:
/gate/source/NAME/setType fastI124 

definition of wiki

FastI124 

FastI124 is a special source implementing a simplified decay scheme of the non-pure beta emitter iodine-124 in which positrons are emitted but not neutrinos, there is no nuclear recoil, gammas are emitted if their emission probability is > 1%; and no atomic de-excitation occurs (no x-rays, Auger electrons). These simplifications allow for an increase in speed with respect to the ion source while retaining important features of iodine-124, i.e. gammas may be emitted concurently with positrons to possibly create "dirty" coincidences. Since decay is simulated, branching ratios are respected hence no activity compensation is necessary. 

The source takes care of particle definitions (gamma, positron) and energy distribution so that there is no need to specify a particle or mention its energy.



For the Cobalt like say Park MinJae you you can using superposition of several source of different energy.

For the database of energie you can try http://nucleardata.nuclear.lu.se/nucleardata/toi/index.asp i don't know if it's that you want
