An approach to incorporate multiple forms of iodine in radiological consequence analysis.

Interest is increasing in the radiological consequences of a release of aerosol and gaseous iodine, especially after the Fukushima accident and also because of new interpretations of the results of recent severe accident experiments. This work provides a brief review of the history of iodine chemistry in containment and suggests an approach to include gaseous iodine, namely in the forms of elemental iodine and organic iodide, in consequence analyses using the MACCS code. As dry deposition is an important characteristic to distinguish each chemical form of iodine when performing a consequence analysis, the mechanisms and mathematical formulas expressing dry deposition are also investigated.

Non-thermal atmospheric pressure plasma preferentially induces apoptosis in p53-mutated cancer cells by activating ROS stress-response pathways.

Non-thermal atmospheric pressure plasma (NTAPP) is an ionized gas at room temperature and has potential as a new apoptosis-promoting cancer therapy that acts by generating reactive oxygen species (ROS). However, it is imperative to determine its selectivity and standardize the components and composition of NTAPP. Here, we designed an NTAPP-generating apparatus combined with a He gas feeding system and demonstrated its high selectivity toward p53-mutated cancer cells.
