Considering current controversies regarding the health effects of low doses of ionizing radiation, study of the high background radiation areas such as Ramsar, Iran can help scientists better evaluate the validity of linear no-threshold (LNT) hypothesis. Ramsar is a coastal city in northern Iran with some areas known to have the highest levels of natural background radiation in the world. The m...

Surveys of the small mammal populations of two coastal wetlands in Ghana, Muni-Pomadze (Central Region) and Keta (Volta Region), were undertaken over a 1-month period as part of an assessment of the ecological status of these wetlands. The study investigated aspects of the ecology of the small mammals, which are known indicators of habitat (environmental) quality. The methodology involved live-...
