We propose a new method to measure the (222)Rn concentration in a closed bore-hole and to use the results for estimation of the diffusion parameter and the average radium content of the surrounding geological formations. In a closed bore-hole, only several meters from the surface, the radon concentration is rather constant (in the +/-15% range) under different meteorological conditions. The inf...
background: everyone is exposed to radon because it is present everywhere with varying concentrations. radon and its progeny are well established as lung carcinogenic. materials and methods: track etch technique using lr-115 plastic track detectors has been used to measure the effective radium content and radon exhalation rates in soil samples collected from urban area of etah district of uttar...

BACKGROUND Radium-223 prolongs overall survival in patients with castration-resistant prostate cancer (CRPC) and symptomatic bone metastases, regardless of prior docetaxel. Whether or not chemotherapy can be safely administered following radium-223 treatment is of clinical importance. An exploratory analysis of prospectively collected data, from the ALSYMPCA (ALpharadin in SYMptomatic Prostate ...
