The amount of radioactive isotopes in submerged Ceratophyllum demersum plants samples were estimated using passive track detector CR-39. collected from four selected sites along the Tigris River Baghdad city, on a monthly basis for one complete year 2019. Certain factors like radon concentration (Bq.m-3), radium content (Bq.kg-1) and uranium (ppm) evaluated. average values 222Rn level, 226Ra 23...

BACKGROUND Myelosuppression is common in patients with progressive castration-resistant prostate cancer and bone metastases. Radium-223 prolongs overall survival in these patients but may cause myelosuppression; understanding risk factors will improve clinical decision making. We describe hematologic safety of radium-223 in ALSYMPCA and post hoc analyses identifying patients at increased risk f...

IN THE years 1903 and 1904, shortly after the discovery of radium, small amounts of radioactivity were discovered in the water of the health springs of the spas of Germany and France. It was found that this radioactivity was due to radon, a gaseous daughter-product of radium. The supposed medicinal benefit from drinking of, or bathing in natural springwater was ascribed to the radon. A medical ...

BACKGROUND Radium-223 dichloride, or radium-223, is a first-in-class alpha emitter that selectively targets bone metastases with high-energy, short-range alpha particles and is approved for the treatment of patients with castration-resistant prostate cancer (CRPC), symptomatic bone metastases, and no known visceral metastatic disease. Nurses are essential in educating patients about radium-223....

The measurement of short-lived Ra often involves a second measurement for supported activities, which represents Ac in the sample. Here we exploit this fact, presenting a set of 284 values on the oceanic distribution of Ac, which was collected when analyzing water samples for short-lived radium isotopes by the radium delayed coincidence counting system. The present work compiles Ac data from co...

BACKGROUND Radium-223 dichloride (radium-223), an alpha emitter, selectively targets bone metastases with alpha particles. We assessed the efficacy and safety of radium-223 as compared with placebo, in addition to the best standard of care, in men with castration-resistant prostate cancer and bone metastases. METHODS In our phase 3, randomized, double-blind, placebo-controlled study, we rando...

Uncontrolled disposal of oilfield produced water in the surrounding environment could lead to soil contamination by naturally occurring radioactive materials (NORM). Large volumes become highly contaminated with radium isotopes (226Ra and 228Ra). The concentration radionuclides 226Ra, 232Th 40K were determined using gamma ray spectrometry order assess radiological health hazards excess lifetime...
