The Challenge: Perspectives and reflections on the public reaction to recent Fukushima‐related radionuclide studies, and a call for enhanced training in environmental radioactivity

In Response: An academic perspective Recent scientific publications addressing the release of radionuclides into the Pacific Ocean from the damaged Fukushima nuclear reactor in Japan, and in particular their bioaccumulation in marine fish (including some that have migrated to the west coast of United States), have received remarkable public interest and extensive media attention. Most concern ...

Comparing policy, regulations and institutions for geological disposal of radioactive waste and carbon dioxide

This paper compares the policy, regulatory and institutional (PRI) settings of Radioactive Waste (RW) and Carbon Dioxide (CO2) disposal for selected countries. This comparison is premised on the following arguments: (a) the policy/political acceptance of nuclear power and coal power with Carbon Capture and Storage (CCS) technology to redress the climate change challenge will be essentially ...

Lysimetric studies for modelling radioactive contaminant transport in soils

To assess the movement of contaminants in the soil mass surrounded by near/subsurface waste repository, researchers have developed several mathematical and numerical modelling techniques. However, most of these techniques consider remolded state of soil mass, which fail to reproduce exact in situ conditions and also have used inactive salts as model contaminants. Hence, in order to model ...

Radiometric ratings for phosphogypsum in industrial areas in Romania

In order to assess the potential environmental risk of phosphogypsum and to establish a future and proper pollution management plan of gyp–stacks and waste dumps resulted due to the operation of former chemical plant, several types of measurements have been made. This paper presents the atmospheric radon concentrations measurements for phosphogypsum deposits in three areas of chemical industry. ...

Environmental toxicity and radioactivity assessment of a titanium processing residue with potential for environmental use

Thorough examination of the physico‐chemical characteristics of a Ti processing residue was undertaken including mineralogical, geochemical, and radiochemical characterisation, and an investigation of the environmental toxicity of softwater leachate generated from the residue. Concentrations of most metals measured in the leachate were low; thus, the residue is unlikely to leach high levels of ...

Socio–environmental nuclear conflicts: the case of El Cabril

Since the commissioning of the 'El Cabril' Central Storage Facility for Low– and Intermediate–level Radioactive Waste (hereafter 'El Cabril'), most people living in nearby towns and villages have regarded this nuclear facility with a marked degree of rejection and distrust. This study examines the process of analysis, management and intervention specifically designed and implemented with a view ...

External and internal radiation doses due to alpha activity in Tafila district, Jordan

Tafila district of Jordan is unique in the presence of phosphate mines and hot spa which are the major sources of natural radioactivity. Natural radionuclides transfer from soil to vegetables grown in the region, and become a part of people's food. In this study, 16 soil and vegetable samples from Tafila district were collected from eight locations. External absorbed dose rates were calculated to ...

Establishment of a radioactive contamination index in seawater from the Gulf and Pacific coasts in Mexico

This paper intends to establish one radioactive contamination index in seawater based on the relation A1/A2, where A1 is the radioactivity due to the contaminant radioisotope 137Cs and A2 is the radioactivity due to the natural radioisotope 40K, both expressed either as Bq/l in seawater or Bq/g in sea salt. At a second step, the same volumes of marine sediments were detected, but in this case ...

The 'threat' of radioactivity: how environmental education can help overcome it

For environmentalists, nuclear power and environmental preservation are two antagonistic ideas. They cannot accept that nuclear power is capable of supplying huge amounts of energy with the least impact on the planet. As a result, the public is misled by environmental Cassandras who prognosticate doom for a world with nuclear reactors. Inevitably, other nuclear projects, like research reactors ...

On the new parameterisation of the eddy diffusivity for radioactive pollutant dispersion

In the present work, starting from the evolution equation for the turbulent energy density spectrum, we develop a new model for the growth of the turbulence in convective boundary layer. We apply dimensional analysis to parameterise the unknown inertial transport and convective source term in the dynamic equation for the three-dimensional spectrum. The non-linear integro-differential equation is ...

Huge Price Increases Underway from Lamp Manufacturers: The impact of rare earth metals shortages

Brace Yourself for Record Price Increases from the Lamp Manufacturers. As we first reported in June, there is a rapid, emerging shortage of rare earth metals, a primary component used in the manufacture of fluorescent lamps - principally phosphors. Phosphors are transition metal compounds or rare earth compounds of various types. The most common uses of phosphors are prevalent in green ...

Equilibrium adsorption isotherm of U(VI) at pH 4 and pH 5 onto synthetic magnetite nanoparticles

The adsorption features of synthetic magnetite nanoparticles have been investigated for removal of uranyl ions from nitric solutions. These magnetic nanoparticles can be used to adsorb contaminants in wastewater and can subsequently be removed from the medium by a magnetic process because of their superparamagnetic behaviour. The magnetite nanoparticles were synthesised by simultaneous ...

Outline of a public health risk assessment method

An index for the integral characterisation of risk is necessary for improving risk management, comparing the effects of various practices on the environment and keeping risk as low as reasonably achievable while allowing economic development. Based on the previous concepts of public health risk assessment and radiation protection assessment and from the viewpoint of risk management, this paper ...

Radioactivity and scrap: Time to share the burden

The melting of metals containing a radioactive source can have devastating health, environmental and financial implications. But according to leading lights within the recycling industry, scrap processors do not receive adequate support from governments, among others, in tackling this monumental challenge. The industry’s concerns were highlighted at a workshop dedicated to the subject at the BIR ...
