ROENTGEN RAY INTOXICATION

Roentgen Ray Intoxication

These experiments show that the common laboratory animals are about equally sensitive to the x-ray given over the abdomen. The clinical reaction following a M.L.D. is very similar and the intestinal pathology almost identical. The rat and guinea pig are slightly more sensitive to the x-ray than are the dog, cat, and rabbit. By contrast birds, frogs, and reptiles are very resistant to the x-ray ...

A Study of Renal Function in Roentgen Ray Intoxication

Our experiments give no support to the current belief that an x-ray nephritis may be produced by direct or indirect action of the hard Roentgen rays. Moderate doses of x-rays given repeatedly over considerable periods of time have no demonstrable influence on renal function or renal structure. With x-ray exposures of the abdomen and shielding of the kidneys fatal intoxication may be produced wi...

Roentgen Ray Intoxication. Iii . T~e Path of a Beam O]~ Hard Rays in Txe Living Organism

l%A~ 45. All roentgenologists are deeply interested in the problems which may be formulated in these few questions: Do the hard x-rays follow a straight and narrow path from the x-ray target through the tissues of the human body? Do these hard x-rays suffer from reflection or refraction and therefore influence tissues outside of this direct path-way? What factor is secondary radiation in the tr...

Ii. Aplasia of Marrow and Fatal Intoxication in Dogs Produced by Roentgen Radiation of All Bones

Constant findings were obtained in the acute reaction to the specified amount of heavily filtered radiation over the bony skeleton. 1. There develops without warning a short and fatal intoxication on the 8th or 9th day after the exposure to the radiation. 2. A profound leucopenia appears after 5 to 6 days and is maintained in the peripheral blood (200 white blood cells or less per c. mm.) for t...
