ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

In a series of experiments, the dosimetry of OBT in the mice supplied with THO or OBT directly or indirectly from their mothers was studied. In the offspring mice nursed by mother mice supplied with THO as drinking water, the largest contribution of OBT to the total accumulated dose was found in the brain. The percent contribution of OBT to the total dose distributed between 17 and 42% among various soft tissues. The OBT localization to cell nuclei increases the microscopic dose to cell nuclei by a factor of 3 – 6 in the case of DNA-bound tritium in comparison with the dose estimated from the tissue-averaged tritium concentration. The tritium localization is of less importance in the case of protein-bound tritium. The blood level tritium was found to be useful and convenient for OBT dosimetry in a practical case of radiation protection of humans after acute and chronic intake of tritium. A new technique was developed to isolate mouse red bone marrow from tibia. A model experiment using mice has shown that the dose to red bone marrow in the case of oral THO intake was lower than the dose estimated for the blood pool.
