Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

That gave me a better insight of what is happening, I appreciate your help!
It turns out that in the step I spoke about, photoelectric absorption is taking place. If I am not wrong 33.164 keV is binding energy of Iodine and a photon with energy 149.14 keV delivers 116 keV to electron (116=149.14-33.164). My interpretation is right? Please see attached text file.
Also, I see "NaI_Scint phot" reflecting photoelectric effect occuring at position (3.82,0.12,-19.6) (Row 7 of tracks2.txt). Then what does "0 and 0.0332" as kinE and dE reflects? I know that the values I should be taking for my interpretation are in Row 8 (149 and 33 keV), but what are "0 and 0.0332" then?
Lastly, why I don't see any StepLeng and TrackLeng in Row 8? How are Row 7 and Row 8 different?
