• O. Rahn (1934) "The physico-chemical basis of biological radiations", Cold Spring Harb. Symp. Quant. Biol. 2:226-240, doi:10.1101/SQB.1934.002.01.029. [web] https://symposium.cshlp.org/content/2/226.extract
• The free excerpt was read. The full-text PDF link may be behind a paywall (not tried). The volume table of contents is at http://library.cshl.edu (symposia 1934 contents): Rahn is at p.226, followed by Hugo Fricke on X-rays (p.241).
• Excerpt (Rahn's words, short quote) [web]: "it smacks of mystery and witchcraft, of miraculous healing and metapsychics". He goes on to say that mitogenetic radiation "is not of mysterious, but of physicochemical, origin" and presents it as part of the heat of reaction (combustion, neutralization) that "need not necessarily appear as heat".
• Bearing: the inventor's own statement of claims 2 and 3 (the radiation is a share of the reaction energy). It is the 1934 conference version of Chapter II. The published discussion after the paper, if printed, would record what his peers said at the time.
