Exposure to radioactive elements or having them through drinking water causes many biological risks. Therefore, it is important to investigate the drinking water especially in regions where people depend on well water for drinking. Concentrations of some radionuclides in some water wells, in Arar city of Saudi Arabia, were measured by using Hyper Pure Germanium (HPGe) Detector. Concentrations o...

background: the presence of radionuclides in the soil, measures need to be taken to minimize the radiation dose to humans. it is mostly gamma-emitting radionuclides that contribute to the radiation dose in long term behavior of these radionuclides in soil may determine the extent to which such countermeasures need to be applied. materials and methods: the activity concentration of these radionu...

The migration of radionuclides from a borehole repository located about 20 km from the Akwapim fault line which lies in an area of high seismicity was analyzed for some selected radionuclides. In the event of a seismic activity, fractures and faults could be rejuvenated or initiated resulting in container failure leading to the release of radionuclides. A numerical model was solved using a two-...

Artificial radionuclides in the marine environment pose a significant concern along various political, health and environmental aspects since they were introduced as a by-product from the nuclear weapon testing, particularly in the northwestern Pacific Ocean. While radiological concern is confined only in special cases, the introduction of artificial radionuclides has been proven to be very use...

In November 2013, a new EURATOM Directive was issued on the protection of public health from the radionuclide content in drinking water. After introducing the contents of the Directive, the paper analyses the hypotheses about drinking water ingestion adopted in documents of international and national organizations and the data obtained from national/regional surveys. Starting from the Directive...

Variations of Fukushima-derived radionuclides ((90)Sr, (134)Cs and (137)Cs) in seawater and biota offshore Fukushima and in the NW Pacific Ocean were investigated and radiation doses to the Japanese and world population from ingestion of seafood contaminated by Fukushima radionuclides were estimated and compared with those from other sources of anthropogenic and natural radionuclides. The total...

We describe for the first time the synthesis of biocompatible TiO2 nanoparticles containing a functional NH2 group which are easily dispersible in water. The synthesis of water dispersible TiO2 nanoparticles coated with mercaptosuccinic acid is also reported. We show that it is possible to exchange the stearic acid from pre-synthesised fatty acid-coated anatase 5-nm nanoparticles with a range o...

Painful osseous metastases are the major cause of cancer-related pain in metastasized prostate cancer. In hormone refractory prostate cancer multiple painful metastases can be treated with radionuclides. Initially, Strontium-89 was successfully used for pain palliation with pain relief in more than half the patients. More recently, radionuclides with shorter physical half-lives such as Rhenium ...
