BACKGROUND In the porcine overstretch injury model of restenosis, endovascular beta-radiation reduces neointima formation. To determine whether this therapy could be applied to patients with coronary artery disease, a special device was developed to allow delivery of 12 encapsulated 90Sr/Y sources, measuring a total of 30 mm, to various sites within the coronary arterial tree. This study was de...

sir, the big flooding in thailand in 2011 is one of the problematic flooding in asia. it causes several destroying to many things in the disaster areas. an important concern is on the effect on the setting with the radioactive elements usage. in thailand, there are some places with radioactive elements including to the university, hospital as well as radioactive research center. luckily, during...

The in-situ characterisation of strontium-90 contamination groundwater at nuclear decommissioning sites would represent a novel and cost-saving technology for the industry. However, beta particles are emitted over continuous spectrum it is difficult identify radionuclides due to overlap their spectra lack characteristic features. This can be resolved by using predictive modelling perform maximu...

the present nuclear leakage crisis from japan is a topic to be discussed in present public health. in radiology, the leaked radioactive elements are considered hazard. here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. based on previous similar nuclear crisis in russia, it is eviden...

In this paper, experiences of the last 20 years with PERALS-technique are described. PERALS stands for photo electron-rejecting alpha liquid scintillation. This scintillation technique was developed by Jack McDowell in 1970s and is a powerful analyses many natural nuclides also beta nuclide 90Sr. The principle based on selective extraction radionuclide from water phase means complexing or ion p...

Coastal areas in Minami-soma City, Fukushima, Japan, were seriously damaged by radioactive contamination from the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident that caused multiple pollution by tsunami and radionuclide exposure, after the Great East Japan Earthquake, on 11 March 2011. Some areas will remain no-go zones because radiation levels remain high. In Minami-soma, only 26 perce...

T his document provides an overview on the recent advances in Europe concerning the long-term environmental behaviour of radionuclides. It describes and illustrates the most significant scientific achievements gathered through three European projects, PEACE, LANDSCAPE and EPORA, which have been co-funded by the European Commission (DGXII) under the Nuclear Fission Safety Programme. The improvem...
