<pre>Dear all,</pre>
<pre> </pre>
<pre> Well , I have doubts. </pre>
<pre><br />I would like to define Barium-133 source ( half life : 10.539 a ) .Then, I did, as the exemplo as iodine. Ba-133 (half life 332578443.114 s )<br />But, It presents mistake like : </pre>
<pre>[G4-cerr] parameter value (s ) is not listed in the candidate List.<br />[G4-cerr] ***** Illegal parameter (1) </gate/source/Ba/setForcedHalfLife 332578443 s > *****</pre>
<pre> </pre>
<pre> </pre>
<pre>Why is it?</pre>
<pre> </pre>
<pre><strong>Exemplo similar like iodine</strong> :</pre>
<pre> </pre>
<pre>#=====================================================<br /># Source - Ba-133 <br />#=====================================================<br /><br /><br />/gate/source/addSource Ba <br />/gate/source/Ba/gps/type Volume<br />/gate/source/Ba/gps/shape Cylinder <br />/gate/source/Ba/gps/radius 0.2 cm <br />/gate/source/Ba/gps/halfz 0.15 cm <br />/gate/source/Ba/attachTo movsource<br /><br />/gate/source/Ba/gps/particle ion<br />/gate/source/Ba/gps/ion 56 133 0 0 <br />/gate/source/Ba/setForcedUnstableFlag true<br />/gate/source/Ba/<strong>setForcedHalfLife 332578443 s</strong> <<<<<<<<<<< when put it<br />/gate/source/Ba/gps/energytype Mono<br /><br />/gate/source/Ba/gps/monoenergy 0. MeV<br />/gate/source/Ba/setActivity 3665.51 becquerel <br />/gate/source/Ba/gps/angtype iso<br /><br />/gate/source/list<br /><br />=======================================================================</pre>
<p>Another case :</p>
<p> But, when I use the follow codigo (below ) with setForcedHalfLife , its ok. :</p>
<pre># Source - Ba-133</pre>
<pre><br />/gate/source/addSource Ba <br />/gate/source/Ba/gps/type Volume<br />/gate/source/Ba/gps/shape Cylinder <br />/gate/source/Ba/gps/radius 0.2 cm <br />/gate/source/Ba/gps/halfz 0.15 cm <br />/gate/source/Ba/attachTo movsource<br /><br />/gate/source/Ba/gps/particle ion<br />/gate/source/Ba/gps/ion 56 133 0 0 <br />/gate/source/Ba/setForcedUnstableFlag true<br />/gate/source/Ba/useDefaultHalfLife <<<<<<<<<<<<<<<<< I put that instead of setForcedHalfLife</pre>
<pre>/gate/source/Ba/gps/energytype Mono<br />/gate/source/Ba/gps/monoenergy 0. MeV<br />/gate/source/Ba/setActivity 3665.51 becquerel <br />/gate/source/Ba/gps/angtype iso<br /><br />/gate/source/list</pre>
<pre> </pre>
<pre> </pre>
<p>Then, I have a doubt because I see :</p>
<pre>GateSourceMgr::ListSources: List of the sources in the source manager</pre>
<pre>Source --------------> Ba<br /> ID : 0<br /> type : gps<br /> activity (Bq) : 3665.51<br /> startTime (s) : 0<br /> time (s) : 0<br /> forcedUnstable : 1<br /><strong>forcedHalfLife (s) : 3.32964e+08</strong><br /> verboseLevel : 0<br /> relative to vol : movsource<br />---------------------- </pre>
<p> </p>
<pre>When I saw this force Half Life (s) : 3.32964e+08. I have doubt if it is ok. How does Gate 8 determine this?</pre>
<p> </p>
<p>Kind regards, </p>

<div>Hi, Jeffrey Agyapong,</div>
<div>this is an example, how to simulate an Iodine-131 source, with Iodine defined</div>
<div>by Z= 53 and A = 131</div>
<div>For Technetium-94 it has to be</div>
<div>Z=43, A = 94</div>
<div>See below for details.</div>
<div>Kind regards,</div>
