Angiogenesis is an essential process in solid tumours growing beyond 2 to 3 mm3, since diffusion is no longer sufficient to supply the tissue with oxygen and nutrients. Integrins αvβ3 have been shown to play an important role in a series of pathological processes including angiogenesis and tumour cell metastasis. It has also been shown that peptides based on the Arg-Gly-Asp (RGD) sequence have...

It is well known that iron ions have a strong impact on the labeling efficiency of DOTA-peptides with 68Ga. In a draft for a monograph of 68Ga-chloride for the European Pharmacopoeia (PHARMEUROPA, Vol. 23, No. 3, July 2011) a maximum concentration for iron is given with 10 µg/GBq. The concentration should be determined by atomic absorption spectrometry.

Sr-90 is a long-lived radionuclide (T(1/2) = 28.6 a), produced as a by-product in nuclear power plants. Due to its chemically similarity to calcium, it follows the food chain from environment (e.g. aquatic systems and soil) to fauna and human in case of release in the biosphere. Strontium can be, as well as calcium, incorporated in bones. Stable isotopes of strontium might not be harmful, but...

The process of isolation of no-carrier added 177Lu produced via 176Yb(n,gamma)177Yb - 177Lu from mixture containing macroscopic amounts of the ytterbium target material was investigated. For this purpose a novel method of electrochemical selective amalgamation of ytterbium from 177Lu/Yb mixture into mercury-pool cathode was applied. The electrolyte solution contained mixture of 20 mg ytterbium...

A KBS-3-type repository for the spent fuel from the Finnish nuclear power reactors in Olkiluoto and Loviisa is to be built in the bedrock at the Olkiluoto site at the depth of approximately 400 m. The final disposal plan includes a safety assessment of the spent nuclear fuel, where the potential dose contributing nuclear waste nuclides for man are specified. As a part of this assessment, the...

Radioactive waste poses a serious danger to the environment. Consequently, many significant efforts are made to ensure the safe disposal of hazardous waste. In order to assess the long term safety of a repository, geochemical model calculations are used to analyze the performance of a system and predict the amount of radionuclides potentially mobilized from a repository. For reliable...

Sorption processes on mineral surfaces play an important role in the retardation behaviour of radionuclides and have to be considered in performance assessment calculations. However, almost all available experimental data are restricted to low ionic strength conditions. Saline conditions are not restricted to solutions relevant to rocksalt formations. Elevated salt concentrations up to 6.5 M...
