Production and Application of Radionuclides
Poster
The need for toxicity assessment of industrially relevant nanoparticle materials implies that in vitro and in vivo biokinetics studies are required. Radiolabelled nanoparticles are an excellent candidate for such biodistribution measurements and are also of high interest for particle tracing and fate studies in other areas.
We describe here an external target system for direct activation of...

Cu isotopes (e.g. Cu-64) increasingly find use in radiopharmaceutical applications, accordingly fast and reliable methods for the production of these isotopes are needed. Aim of the presented project is the characterization of a Cu selective extraction chromatographic resin for the fast and selective separation of Cu radionuclides e.g. from irradiated Ni targets. The characterization of the...

Decontamination technologies are generally developed to reduce the collective dose of the maintenance and operation personnel at NPPs. The highest efficiency (i.e., the highest DF values) available without detrimental modification of the treated surface of structural material is the most important goal in the course of the application of a decontamination technology. The AP-CITROX procedure...

Evaluating the water chemistry in the primary circuit and the effect of chemical decontamination of the heat exchanger tubes performed by the AP-CITROX (AP: alkaline permanganate; CITROX: citric and oxalic acid) procedure at Paks NPP (Hungary), a project dealing with the comprehensive investigation of the general corrosion state of the steam generators (SGs) has been initiated. Owing to the...

Non-conventional longer-lived PET radionuclides with half-life higher than that of 18F (109 min) are very promising PET tracers for imaging of biochemical processes or body structures requiring slower kinetics. Among them, 124I (4.18 d) plays an important role. Radiochemistry of iodine radioisotopes (123I, 124I, 125I and 131I)...

Cross sections for deuteron induced reactions on natural molybdenum leading to 93Tc, 93mTc, 94Tc, 94mTc, 95Tc, 95mTc, 96Tc, 96mTc, 99mTc, 99Mo, 92mNb, 95Nb and 89Zr were measured in deuteron energy range 9.0–19.6 MeV on the cyclotron U-120M of the Nuclear Physics Institute AS CR. Special attention was paid to excitation function for formation of 95mTc, which is used as a tracer for determining...

Copper has many radionuclides (60Cu, 61Cu, 62Cu, 64Cu, and 67Cu) that can be used in nuclear medicine and molecular imaging. Isotope 64Cu (Iβ+= 17.6 %, Eβ+max=653 keV, Iβ-= 38.5 %, Eβ-max=579.4 keV ) is positron emitters and half life 12.7 hrs and is suitable for the preparation of radiopharmaceuticals for PET imaging. The 64Ni(p,n)64Cu reaction route is popular for its preparation because...

Several procedures of the preparation of the radionuclide 95mTc, a radiotracer useful for vari-ous purposes, were tested. A foil made of natural molybdenum was irradiated with protons or deuterons and after 5-6 weeks of decay the 95mTc radionuclide was separated. Three different separation procedures were tested. 1) Alkaline-oxidative fusion of the Mo target with sodium peroxide and sodium...

Interest to high-spin (16+) long-lived (31 y) 178m2Hf isomer was established since 20 years ago because of a possibility to produce it in a micro-weight amount for consecutive studies of nuclear reactions with high-spin target and for potential application as an energy accumulator. Production of 178m2Hf was described in [1] via spallation of Ta by protons at LAMP facility and via 176Yb(4He,2n)...
