High-level natural radioactivity, geochemical, geological, and radiological hazard assessment of the poorly investigated Wadi Gebeiy Dokhan volcanics rocks are discussed. located in Southwestern Sinai, Egypt, covering an area ~1.3 km2. represented by porphyritic dacite. Geochemically, they have medium-k characters originate from calc-alkaline magma within a arc environment. Along fault plane st...

The uranium (234U/238U) and radium (228Ra/226Ra) activity ratios and 87Sr/86Sr isotopic ratio in thermal groundwater, subsurface water (groundwater) and river water from Poddebice and Uniejow were determined. The uranium and radium activity ratios and strontium isotopic ratio varied from 0.629 to 1.471, from 0.396 to 4.961 and from 0.708438 to 0.710344, respectively. The results for the thermal...

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...

A gamma spectrometric analysis of rock samples collected from the Precambrian Oban Massif, southeastern Nigeria, was performed to determine some primordial radioelements’ activity concentrations: U-238, Th-232, and K-40, their associated radiological hazards. The mean radionuclides determined be 1073.06 ± 0.65, 160.74 1.32, 250.76 0.91 Bq·kg−1 for 40K, 238U, 232Th, respectively, showing that th...

Despite much progress in mCRPC treatment in recent years, optimal treatment sequences are still unclear, particularly in the post-abiraterone or post-enzalutamide treatment space. For men with bone-predominant disease (ie, no visceral or bulky nodal metastases) and symptomatic progression, current offprotocol options include crossover therapy to another oral novel hormonal agent (enzalutamide t...

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...

ntroduction: The purpose of this study was to measure the radioactivity in the agricultural soil of south-east of Shazand Refinery Complex to determine both reliable baseline data on the radiation level and the radiation dose exposure to the farmers and inhabitants of the studied area. Material and Methods: This study was conducted on 21 soil...

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...
