Natural radioactivity is the main source of radiation which affects the human body [1]. Anthropogenic activities (e.g. high-altitude fl ights, mining and living in buildings) have increased the exposure to these sources [2]. In particular, the problem of natural radioactivity in buildings is of great interest since the building materials are of terrestrial origin and they consequently contain s...

Contact-rehydration in terrestrial slugs involves a specific drinking behaviour during which water is rapidly absorbed through the integument of the foot. When dehydrated slugs were placed on wet filter paper containing 14C-inulin, they displayed the characteristic drinking posture and absorbed both water and 14C-inulin. Samples of haemolymph from dehydrated slugs after 12 min of contact-rehydr...

Background: Salivary flow rate (SFR), to estimate salivary gland dysfunction and radioactivity in different body fluids, to evaluate its intensity, were determined in thyroid patients after 131-I therapy. Material and Methods: For determination of SFR an innovative sponge test was adopted and the radioactivity in saliva, blood and serum of thyroid patients was determined by NaI (TI) Scintillati...

This study presents the map of external effective annual dose rate (1:200,000 scale) due to terrestrial and cosmic radiation. The is assessed via gamma ray spectroscopy combining radiometric data from airborne surveys laboratory measurements. geostatistical method Collocated CoKriging used for spatial interpolation sparse data, adopting a high-resolution geological as ancillary information. obt...

Background: Turkey, especially the northern part of it, was one of the countries which were contaminated by the Chernobyl accident.  Rize is a city located in the Northeastern district of Turkey which was heavily influenced by the Chernobyl nuclear accident. Materials and Methods: In this study, the activity concentrations of natural (226Ra, 232Th, 40K) and artificial (137Cs) were measurem...

Only 17 per cent of French households received digital television in 2002. Hence, for public authorities, digital terrestrial television (DTTV) is mainly a means to stimulate the development of digital television. However, cable and satellite operators (TF1, M6 and Canal Plus), which have been designated as leaders of the DTTV process, are reluctant, as they view DTTV as a competitor to their e...

Wireless sensor networks have emerged as a fastgrowing technology that has enabled us to monitor physical and environmental states. As of yet these valuable sensor networks have been bound to terrestrial terrains; however, seventy percent of the Earth’s surface is covered by enormous bodies of water: oceans, seas and rivers. Most of this territory remains unchartered, and this primarily gave a ...
