Quantitative Interpretation of Biological X-Ray Effects.

Mice treated with small doses of x-rays and inoculated with cancer immediately afterwards, show a marked suppression of lymphoid proliferation. If, however, the cancer inoculation is made 7 days after the exposure to x-rays, thus permitting the primary lymphoid stimulation known to occur soon after the x-ray treatment to arise, a second stimulation takes place in a large proportion of mice thus inoculated. Changes in the blood of mice x-rayed and inoculated with cancer 7 days afterwards show that the state of resistance to cancer inoculation is attended by blood lymphocytosis, as is the case in all other varieties of immunity to transplanted cancer so far studied.

Holographic Reconstruction

AbstractThe influence of matrix effects i.e. beam attenuation (BA) and indirect excitation (IE) on local structure imaging with multiple-energy x-ray fluorescence holography is studied using computer simulations. An analytic formalism is developed which allows for the description of BA and IE when the thickness of the sample is arbitrary. It is shown that beyond the thin-sample approximation, in specific cases, the measured holograms cannot be treated as entirely element sensitive. Consequently, it is demonstrated that due to the reduction of element sensitivity, spurious maxima can arise in the holographic reconstruction which can be misinterpreted as atomic images. The proposed formalism allows one to analyse BA and IE and to correct for them. It opens way for quantitative interpretation of x-ray fluorescence holograms.
