37 " If we ascribe the ejection of the proton to a Compton recoil from a quantum of 52 x 106 electron volts, then the nitrogen recoil atom arising by a similar process should have an energy not greater than about 400,000 volts, should produce not more than about 10,000 ions, and have a range in the air at N.T.P. of about 1-3mm. Actually, some of the recoil atoms in nitrogen produce at least 30,000 ions. In collaboration with Dr. Feather, I have observed the recoil atoms in an expansion chamber, and their range, estimated visually, was sometimes as much as 3mm. at N.T.P.These results, and others I have obtained in the course of the work, are very difficult to explain on the assumption that the radiation from beryllium is a quantum radiation, if energy and momentum are to be conserved in the collisions. The difficulties disappear, however, if it be assumed that the radiation consists of particles of mass 1 and charge 0, or neutrons. The capture of the a-particle by the Be9 nucleus may be supposed to result in the formation of a C12 nucleus and the emission of the neutron. From the energy relations of this process the velocity of the neutron emitted in the forward direction may well be about 3 x 109 cm. per sec. The collisions of this neutron with the atoms through which it passes give rise to the recoil atoms, and the observed energies of the recoil atoms are in fair agreement with this view. Moreover, I have observed that the protons ejected from hydrogen by the radiation emitted in the opposite direction to that of the exciting a-particle appear to have a much smaller range than those ejected by the forward radiation.This again receives a simple explanation on the neutron hypothesis.

40 " In his recent guest editorial, Richard McNally voices skepticism about the National Vietnam Veteran’s Readjustment Study (NVVRS) data reporting that over one-half of those who served in the Vietnam War have posttraumatic stress disorder (PTSD) or subclinical PTSD. Dr McNally is particularly skeptical because only 15% of soldiers served in combat units (1). He writes, “the mystery behind the discrepancy in numbers of those with the disease and of those in combat remains unsolved today” (4, p 815). He talks about bizarre facts and implies many, if not most, cases of PTSD are malingered or iatrogenic. Dr McNally ignores the obvious reality that when people are deployed to a war zone, exposure to trauma is not limited to members of combat units (2,3). At the Operational Trauma and Stress Support Centre of the Canadian Forces in Ottawa, we have assessed over 100 Canadian soldiers, many of whom have never been in combat units, who have experienced a range of horrific traumas and threats in places like Rwanda, Somalia, Bosnia, and Afghanistan. We must inform Dr McNally that, in real world practice, even cooks and clerks are affected when faced with death, genocide, ethnic cleansing, bombs, landmines, snipers, and suicide bombers ...One theory suggests that there is a conscious decision on the part of some individuals to deny trauma and its impact. Another suggests that some individuals may use dissociation or repression to block from consciousness what is quite obvious to those who listen to real-life patients." Cameron, C., & Heber, A.
