THE presence of long-lived radioisotopes, for example strontium-90 and cæsium-137, in fall-out material and their detection in soil, vegetation and animal products have been confirmed 1.

The Defence Department concluded in the ’70s that the soil was so contained with cesium-137 and strontium-90 – both taking about three decades to decay, called a half-life – that the best ...

In this study, Strontium has been doped in ZnO to form a nanostructure ... with 4% doping of Sr in ZnO nanostructures, and at 90°C process temperature, generated an output voltage of 7.08 mV, an ...

This program is useful for visualizing approximations of energy band diagrams, and performing back-of-the-envelope calculations of their important parameters. Energy bands can be modeled at varying ...
