The International Commission on Radiological Protection (ICRP) system of protection consists of existing, planned, and emergency exposure situations. With the 2007 Recommendations in ICRP Publication 103, a coherent approach has been established that emphasises the optimisation of protection with appropriate constraints or reference levels in each exposure situation. Existing exposure situation...

In this study, the insecticidal activity of native diatomaceous earth (DE) Turco004 was tested against pupae Potato tuber moth, [Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)] in laboratory conditions. bioassays were used dust formulation and applied four concentrations (2.5, 5, 10 20g/m2) DE. Pupa weights number adults emerging from recorded after 24, 48, 72, 96, 120, 144 168 hou...
