This article describes and assesses the security of transport radioactive nuclear material in Belgium that has been boosted after terrorist attacks Brussels 2016. The looks at different possibilities on transports possible consequences: theft for use a exposure device, dispersal or an improvised weapon; conventional attack transport, releasing radiation into environment. focus insider threat is...

1 INSTRODUCTION In the concept of geological radioactive waste disposal, argillite is being considered as a possible host rock in various countries such as France and Switzerland. This material is chosen thanks to its extremely low permeability that is required to limit the transfer of radioactive elements from the waste package towards the environment. During the construction and exploitation ...

This effort is a continuation of the work of Task 3 (see pages 10 and 11), and the same overview applies. Advanced nuclear processes such as the transmutation of nuclear waste, fast reactors, liquid-metal-cooled reactors, and spallation neutron sources require advanced materials systems to contain them. The required structural materials must be stable in the presence of nonmoderating coolants. ...

The physical protection of nuclear material and nuclear facilities is a highly mature field, dating virtually from the inception of the nuclear age, with longstanding international requirements and guidance. While the international community, including both the IAEA and Member States, has achieved much progress within the decade since approval of the Code of Conduct, the security of radioactive...

Leaching of metals from cement under various environmental conditions was measured to evaluate their environmental safety. A cement product containing clinker, which was produced from cement kiln co-processing of hazardous wastes, was solidified and leaching of metals was characterized using the 8-period test. Concentrations and speciation of metals in cements were determined. Effects of ambien...

1. Mouse mast-cell tumours P815 Y and HC were shown to contain glycoprotein material composed of glucosamine, galactosamine, sialic acid, galactose and mannose. 2. The major amino acids released after acid hydrolysis of Pronase-treated digests of the glycoprotein are aspartic acid, glutamic acid, serine, threonine, proline, glycine and alanine. The Pronase-digested material is not degraded in a...

The observations in this work suggest that with certain doses of radioactive material, the fundamental damage in the lymphoid tissues is to the stem cell and that the damage is to the chromatin of the nuclei of these cells. The erythroid tissues are apparently less susceptible to radioactive material than the lymphoid tissues but an original anemia of secondary type from peripheral destruction ...
