recurring after a short time, was successfully treated by radium. It is interesting to note in the present series (Cases 3 anid 4), the dlifference in response to radium of two growths which histologically are very similar. Generally it would seem if the situation of the growth is such that it (loes not reaclily permit of removal of a wedge of normal tissue together with the tumour, surgical in...

In medicine, assigning priorities for original ideas and for first implementation of a new type of treatment or technology-radium afterloading, for example-is often difficult. This situation is certainly true for radium therapy, with conflicting claims coming from France, Germany, and the United States about who first implemented it. Moreover, if possible, a distinction must be made between the...

We explore the use of Granular Activated Carbon (GAC) as a mitigation technique for the treatment of drinking water that was artificially enriched with Rn-222 in laboratory by placing a radium rich granite stone (pitchblende) in a closed container filled with tap water for several days in order to allow Rn-222 concentration to approach its highest possible level. Granular Activated Carbon (GAC)...

Although elevated indoor radon concentration can occur almost anywhere, some areas of the U.S. have a much higher fraction of homes with elevated levels than do other areas. Knowledge of what areas tend to have elevated indoor concentrations would allow education and regulatory measures (such as required housing construction techniques) to be focused on populations most at risk from radon. In t...

background: vegetation (food stuff) is grown in soil that contains many radioactive elements such as 238u (uranium), 232th (thorium) and 40k (potassium), which may get deposited either due to radioactive fallout or/and by absorption from the soil and can pose serious health hazards. materials and methods: natural radioactivity, radiological hazards and annual effective dose assessment was carri...

Indoor radon concentrations were measured in four well-known spas of Tunisia using nuclear track detectors. The radon concentrations in these spas were found to be in the range of 19 − 870 Bq.m-3. The equilibrium factor F between radon and its progeny was found to vary in the range of 0.2 0.5, depending upon the ventilation rates within the buildings of the spas. Using the exposure-dose convers...

As each year ushers in new and innovative survivalenhancing treatments for castration-resistant prostate cancer with bone metastases, patients and their physicians have a sense of empowerment associated with this growing therapeutic arsenal.1-5 Nonetheless, nearly 30,000 men still die from prostate cancer every year, and many have debilitating illness from osseous involvement. For this latter g...

tau.amegroups.com © Translational Andrology and Urology. All rights reserved. Most patients with relapsed prostate cancer develop metastatic disease and eventually become castration-resistant. Skeletal metastasis is common in castrate resistant prostate cancer and is an independent poor prognostic factor (1). Furthermore, skeletal related events (SRE) such as spinal cord compression, pathologic...

In 1922 the Québec government appropriated $100,000 for the purchase of radium to found an Institut du Radium at the University of Montreal. Opened largely through the initiative and drive of Dr. Joseph-Ernest Gendreau, the institut was the first organization devoted to radium therapy and cancer treatment in Canada. This paper describes the background, origins and development of the Institut wi...

The radiation treatment of intra-oral cancer involves technics combining intra-oral radium applications directly to the primary seat of the disease and external radiation to the glandular regions of the neck. The problem of the primary lesion has been successfully met by electrosurgical methods, radium seed implantations directly into and about the site of the disease, and by heavily filtered r...
