Neutron Irradiation Behavior of Tungsten

Modeling fast neutron irradiation damage accumulation in tungsten

Due to its advantageous physical properties, tungsten (W) is being considered as a candidate structural material in fusion applications. In this paper, we perform stochastic cluster dynamics calculations of irradiation damage accumulation in pure W under fast neutron spectra in up to doses of 1.5 dpa in the 400∼600◦C interval. Our calculations suggest that He bubbles and dislocation loops accum...

Neutron irradiation of SmFeAsO1−xFx

SmFeAsO1−xFx was irradiated in a fission reactor by a fast (E > 0.1 MeV) neutron fluence of 4 × 1021 m−2. The introduced defects increased the normal state resistivity due to a reduction in the mean free path of the charge carriers. This leads to an enhancement of the upper critical field at low temperatures. The critical current density within the grains, Jc, increases upon irradiation. The se...

Thermal Diffusivity of Ceramics During Neutron Irradiation

Radioisotopes produced by neutron irradiation of food.

The use of neutrons for cargo interrogation has the potential to drastically improve threat detection. Previous research has focussed on the production of (24)Na, based on the isotopes produced in pharmaceuticals and medical devices. For both the total activity and the ingestion dose we show that a variety of isotopes contribute and that (24)Na is only dominant under certain conditions. The com...

Effect of hyperthermia before Neutron irradiation on chromosomal damages of human lymphocytes

Due to importance of combination therapies in cancer treatment, this study was performed to find the effects of hyperthermia and neutron irradiation and heir combination on the human lymphocytes. Blood samples were treated separately with 41.5 °C for 30 and 60 minutes, 43 °C for 15 and 30 minutes, as well as 10 cGy neutron irradiation. They also treated with hyperthermia followed by irradiation...
