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.

A Google search (using "CsI attenuation length") was quite frustrating; most sources are discussing relatively small (few centimeter) crystals, and report light yield rather than optical attenuation. Here are a few results
http://pibeta.phys.virginia.edu/docs/publications/ketevi_diss/node37.html says "of the order of 1 m".
http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19730009057_1973009057.pdf is a scanned 1973 report. It reports substantial variation among samples, with attenuation lengths from 20 to 100 cm.
http://www.sbfisica.org.br/bjp/files/v35_741.pdf uses an attenuation coefficient of 0.099 cm-1 (i.e., 10 cm), and cite C. Labanti et al, NIM A 310, 327 (1991) as their source.
