The Action of Radium Emanation on the Vitamines of Yeast
نویسنده
چکیده
Becquerell has observed that p-rays change yellow phosphorus into red form. Ramsey* and Cameron* have shown that the radium emanation has destruotive and partial synthetic actions upon water, carbon monoxide, carbon dioxide, hydrogen chloride, and ammonia. The decomposing action of radium rays on the lecithin molecule has been observed by Schwara,4 Schaper,& and Werner.6 On the other hand, no specific destructive effect was found by Thies’ and Hertwig.* Hardy0 has reported that radium emanation has the power of dissolving and coagulating globulin in acid and alkaline solutions respectively. Dreyer and Hanssenro have shown that the rays of radium coagulate vitellin; but seemingly it has no effect upon albumin.

The Action of Buried Tubes of Radium Emanation on Neoplasias I N Plants
The insertion into an animal tumor of buried capillary glass tubes containing radium emanation presents a comparatively new departure in radium therapy and is undoubtedly destined to play a prominent part in the future development of the whole field of radiotherapeutics. The technique employed on animals and human beings is as follows: Radium emanation, the first active product of decomposition...
متن کاملEmanation from Granite Countertops
Emanation of radon ( 222 Rn) from granite countertops was measured using continuous and integrating radon monitors, and in air collected from encapsulated pieces of the countertops. A majority of the countertops emitted a measurable amount of radon. Although the granites contained the precursors, no thoron ( 220 Rn) emanation was detected. Gamma-ray spectroscopy was used to determine amounts of...

This little volume deals briefly and completely with the properties of radium both from a therapeutic and physical point of view. Briefly dealing with the observations on the various phenomena which lead to the discovery of radium itself, the author passes to the physical properties of the element, and goes into the differentiation between the alpha, beta and gamma rays. The relationship existi...

In our studies on the radiochemical reaction effeeted by the radiations (beta and gamma) from radium emanation in which enzymes are inactivated we have stated that in a given system the chemical change is a function of the product of two variables; namely, the average amount of emanation present, Eo, and time, t. Theproduct of these two variables has been equated to a single variable, W, for wh...
