Saline waters from underground coal mines in Poland often contain natural radioactive isotopes, mainly 226Ra from the uranium decay series and 228Ra from the thorium series. More than 70% of the total amount of radium remains underground as radioactive deposits due to spontaneous co-precipitation or water treatment technologies, but several tens of MBq of 226Ra and even higher activity of 228Ra...

In 1936, almost 4 decades after the discovery of the x-ray and of radium, the German Röntgen Society erected a monument to commemorate all who had died as a consequence of exposure to x-rays or radium. George W.C. Kaye of the US National Physical Laboratory wrote the inscription: “To the röntgenologists and radiologists of all nations, doctors, physicists, chemists, technical workers, laborator...

Metastatic castration-resistant prostate cancer (mCRPC) frequently metastasizes to the bone, often resulting in painful skeletal events, reduced quality of life, and reduced survival. The beta-emitting radiopharmaceuticals strontium-89 and samarium-153 alleviated pain in mCRPC patients with widespread skeletal metastases and have been associated with myelotoxicity. Radium-223, a first-in-class ...

INTRODUCTION A number of drugs have been shown to extend life expectancy in castration-resistant prostate cancer (CRPC). Skeletal related events (SREs) secondary to bone metastases cause significant morbidity for men with CRPC. The α-emitting radiopharmaceutical radium-223 dichloride has been shown to improve overall survival, time to symptomatic skeletal events (SSEs) and quality of life in CR...

This paper aims to estimate a potential radiological risk from different kinds of coals used for domestic heating in Serbia, by measuring the activity concentration radionuclides and radon exhalation rate. The obtained mass rate ranges (5.3 ? 3.1) mBqkg?1s?1 (70.3 9.4) mBqkg ?1s?1 was highest lignite type coal. It is estimated that coal stored basement could contribute up 50 Bqm?3 indoor at gro...

He is currently a research associate at the University of Wisconsin-Madison. He is the recipient of the American Medical Association's Physican's Recognition Award and was also recipient of the Outstanding Gradu...

INTRODUCTION Approximately 10 - 20% of prostate cancer cases ultimately progress to castration-resistant prostate cancer (CRPC), for which there is a poor prognosis and a therapeutic need. Radium-223 dichloride (radium-223 [Xofigo]) is a first-in-class α-emitting radiopharmaceutical shown to significantly prolong overall survival in patients with CRPC with symptomatic bone metastases and no vis...

INTRODUCTION Bone seeking radiopharmaceuticals have been used for decades in the palliation of pain from bone metastases emerging from prostate cancer. Recent clinical evidence has demonstrated an improved survival in men with metastatic castration resistant prostate cancer (CRPC) with radium 223. MATERIAL AND METHODS A review of the literature was performed to identify the role of radiopharm...

We used two short-lived radium isotopes (223Ra, 224Ra) and a mass balance approach applied to the radium activities to determine the nutrient contribution of saline submarine groundwater discharge to the coastal waters of the northern Gulf of Aqaba (Israel). Radium isotope activities were measured along transects during two seasons at a site that lacked any obvious surficial water input. An ons...

Various single or multi-modality therapeutic options are available to treat pain of bone metastasis in patients with prostate cancer. Different radionuclides that emit β-rays such as (153)Samarium and (89)Strontium and achieve palliation are commercially available. In contrast to β-emitters, (223)Radium as a α-emitter has a short path-length. The advantage of the α-emitter is thus a highly loca...
