POV

It shouldn't be deleted, but an actual biography should be put in place! Simesa 18:11, 10 April 2007 (UTC)[reply]

The reference "[1]" to "Cohen's fallacy", http://radlab.nl/radsafe/archives/0202/msg00329.html, goes to a website that no longer exists. Brief searching has not revealed an alternative source.

There is a wayback machine copy from 2007 at: http://web.archive.org/web/20070927041759/http://radlab.nl/radsafe/archives/0202/msg00329.html

The reference "[2]" to the journal Health Physics does not point to the abstract mentioned.

Thus the lede of the first topic ("... debates ... are well known ...") in this supposedly biographical article has become nothing but badly referenced POV. Snezzy (talk) 04:13, 6 January 2011 (UTC)[reply]

Passing of BL Cohen

I've found the obituary for BL Cohen here. Regards, ConradMayhew (talk) 22:55, 19 March 2012 (UTC)[reply]

Thanks for that. Pittsburgh Tribune-Review has a longer one [1]; I'll look at it later to see if there's anything with which to supplement the WP page, unless someone does it first. --Old Moonraker (talk) 06:38, 20 March 2012 (UTC)[reply]

Suspected misrepresentation

== The intro says "Cohen was a staunch opponent of the so-called Linear no-threshold model [...]" which was "considered in the 1980s and 1990s a self-marginalizing posture"; considered by whom? I've been reading his book online and he makes it clear in Chapter 5 that he is simply trying to convey the conclusions of scientific organizations (BEIR and UNSCEAR) that are tasked with studying radiation hazards. Either the intro is misleading, or Cohen is lying about their findings (which I very much doubt). Relevant book quote: "both UNSCEAR[12] and NCRP[19] estimate that risks at low dose and low dose rate are lower than those obtained from the straight line relationship by a factor of 2 to 10. For example, if 1 million mrem gives a cancer risk of 0.78, the risk from 1 mrem is not 0.78 chances in a million as stated previously, but only 1/2 to 1/10 of that"

Later it is said that "Professor Cohen stated [...] that low levels of radiation can have beneficial health effects" but the quote afterward from Cohen does not support this claim. Cohen's book doesn't mention hormesis, either, nor does it ever suggest that low doses of radiation are either beneficial or harmless. If Cohen expressed a belief in hormesis at some point (I doubt it, but I can't read the two offline references for this claim), it would mean that he had changed his mind after publishing his book.
