Семинар ЛЯР по химии 16 июня 2015 г., 15:30, Конференц-зал ЛЯР   Программа: 1. Саркис Карамян (ЛЯР ОИЯИ) «Microstructure manifestations in nuclear reactions with gammas and neutrons» 2. Рамиз Алиев (отд-е Радиохимии, фак-т Химии, МГУ) «Production of medical radionuclides by photonuclear reactions» Аннотация Possibility of production of ¹⁸F, ⁴⁴Ti/Sc, 47Sc, ^195mPt, ^69mZn, ⁶⁷Cu using 55 MeV bremsstrahlung radiation was studied. Yield of products of photonuclear reactions on Ti, Au, Zn, Ga, Na of natural isotopic composition was determined. Separation technices based on chromatography and LLX were suggested for ¹⁸F, ^69mZn, ⁶⁷Cu. 3. Ян Коземпел (Департамент ядерной химии, Чешский технический университет, Прага) «Towards new radiopharmaceuticals for targeted alpha-therapy» Аннотация Alpha emitters decaying through short cascades deposit the majority of released energy in a very small volume. Main disadvantage of this system is that no molecule can withhold the recoil energy of daughter hot atoms generated in such decays. We have focused on the preparation of nanoparticles labelled with Ra-223 that partially retain the recoiled atoms and may ensure proper therapeutical dose targeting. Also basic physical and chemical principles would be discussed.
