OBJECTIVE To assess the level of general practitioners' knowledge concerning radiation doses for patients undergoing common radiological investigations and the associated risks of...

The objective of the revised Reactor Oversight Process is to monitor licensee performance in the areas of reactor safety, radiation safety, and security. This paper describes the NRC’s revised Reactor Oversight Process and how it is used to assess licensee performance against stated objectives in seven areas (or cornerstones) of plant operations. One of the seven cornerstones of the Reactor Ove...

High reliability and operational safety are most important requirements of aerospace products. Structural Safety (Reliability) assessment techniques help to achieve safe designs and also identify effect of uncertainty occur in structural systems of aerospace products. In general the structural safety is evaluated using various statistical methods like Mean Value and Moment Methods. Currently se...

Concerns about the biological effects of space radiation are increasing rapidly due to the perspective of long-duration manned missions, both in relation to the International Space Station (ISS) and to manned interplanetary missions to Moon and Mars in the future. As a preparation for these long duration space missions it is important to ensure an excellent capability to evaluate the impact of ...
