Radium 223 is an alpha-emitting intravenous radiotherapy approved for the treatment of men with metastatic castration-resistant prostate cancer (mCRPC). The approved indication covers men with pain from bony metastatic disease and no visceral involvement; however, questions remain as to optimal patient selection and timing of this treatment relative to other life-extending therapies for mCRPC. ...

The requirements on a neutral current additive tc the heavy water in the SNO project are as follows: water solubility, low inherent radioactivity or the availability of an easy path of purification from thorium and radium, the possibility for easy separation from the water phase and safety. The solution of such an additive is expected to be transparent in the visible range, stable for extended ...

Several papers [1, 2, 3) 2 and Handbooks [4, 5] have been published during the past 20 years dealing with barrier req uirements for shielding against gamma radiation from radium. These publications have usually suggested lead for the barriers because a large proportion of the applications required restricted space and ready transportabi lity of the barrier and gamma-ray source. For h igh-energy...

OBJECTIVES/HYPOTHESIS Nonchordomatous lesions of the clivus are rare entities. Nasopharyngeal radium irradiation (NRI) treatment consists of application of radium to the posterior nasopharynx near the orifice of the Eustachian tubes, an area adjacent to the clivus. Here we present a unique case of a patient with a history of NRI 70 years prior to presentation with a space-occupying clival lesio...

Haemangiomas are benign skin lesions that usually regress spontaneously, but radiotherapy has previously been used to assist the regression and healing of the lesions. Radium and X-rays were used as a treatment for benign skin lesions such as haemangioma until the carcinogenic effect of ionising radiation in humans was described. We report a patient diagnosed with a sarcomatoid carcinoma. Her p...

This study is aimed at assessing radiation hazards associated with natural radioactivity in common building materials used Ho Chi Minh City, Vietnam. Thirty-six samples from eighteen types of were collected to measure activity concentrations using the gross alpha/beta counting system and gamma-ray spectrometry. The alpha beta ranged 94.7 ? 31.3 1045.1 112.3 Bqkg-1 104.9 4.7 834.4 37.1 Bqkg-1, r...

The specific activity and spatial distribution of 238U, 232Th 40K were determined in the surface soil from Lișava uranium mining sector. This sector belongs to Banat district, an historically important area Romania (an with closed mines a radioactive waste dump). Gamma-ray spectrometry using high-purity germanium (HPGe) detector was used measure naturally occurring radionuclides soil. average a...

People use granite in residential buildings on a large scale all around the world. Knowing granite’s radiological characteristics allows for safe of its properties to be maintained over time. Our findings are significant two reasons: first, they may increase public awareness naturally radioactive materials under investigation, and second, necessary establish standards, regulations, management b...
