This approach does not appear to be logical...but I am not a doctor. How will you use the neutron source (AmBe)? First off the AmBe source does not have sufficent flux (n/sec) to create any S-35 or to irradiate anything to this degree.

Also, the S-35 beta radiation is far less lethal (at the sub-cellular level) than alpha. Alpha radiation is being experimented with to kill cancer cells now as it is a high LET (linear energy transfer) radiation.

So I do not know the lethal dose of Sulfur but feel the "tranformation" of sulfur to chlorine though the use of an AmBe source may yeild no effective results.
