The Effect of Nano-Particle Formation on Radiation Resistance of Phosphate Glasses Potentially Suitable for Nuclear Waste Immobilization

Eurasian Chemico-Technological Journal, 2010
The effect of nano-particles on the radiation resistance of glasses potentially suitable for nuclear waste immobilization was investigated. The glasses were investigated by means of EPR, UV-visible optical spectroscopy, RBS and TEM.

Measurement of radon concentrations at Super-Kamiokande

, 1999
Radioactivity from radon is a major background for observing solar neutrinos at Super-Kamiokande. In this paper, we describe the measurement of radon concentrations at Super-Kamiokande, the method of radon reduction, and the radon monitoring system.

Exact reconstruction formulas for a Radon transform over cones [PDF]

, 2013
Inversion of Radon transforms is the mathematical foundation of many modern tomographic imaging modalities. In this paper we study a conical Radon transform, which is important for computed tomography taking Compton scattering into account.

Feasibility and Safety of High‐Dose Proton Re‐Irradiation in Recurrent Pediatric Central Nervous System Tumors: A Single‐Institution Retrospective Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

Radon, From the Ground into Our Schools: Parent/Guardian Awareness of Radon Levels in Vermont Schools [PDF]

, 2018
Introduction. Radon is the leading cause of lung cancer among non-smokers. Ex- posure to radon in schools may be harmful to schoolchildren, faculty, and staff, but there is currently no legislation mandating testing or mitigation of radon levels in ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...
