Determination of lanthanides in agricultural crops by instrumental and radiochemical neutron activation analysis
Mizera, Jiří ; Kučera, Jan ; Řanda, Zdeněk ; Vávrová, M.
The lanthanide elements were measured in soils and agricultural crops collected in an area polluted by emissions from a phosphate fertilizer plant. Concentrations of lanthanides in the soil and crop samples were determined by instrumental neutron activation analysis (INAA). Selected crop samples were also analyzed using radiochemical neutron activation analysis (RNAA) based on alkaline-oxidative fusion of the irradiated samples followed by precipitation of REE oxalates. Elevated levels of lanthanides were found in some samples, especially in wheat chaff and parsley.
Energie předávaná ionizujícími částicemi a inaktivační mechanismus v buňkách
Kundrát, Pavel ; Lokajíček st., Miloš
Energy loss of individual particles, their lateral scattering and energy-loss straggling are involved in the Bragg peak formation. A model of the Bragg peak of protons and light ions is presented that takes into account all these phenomena.
Pravděpodobnostní model popisující inaktivaci buněk ionizujícími částicemi
Kundrát, Pavel
Numerical analysis of experimental data concerning cell inactivaton by protons is presented, showing feasibility of the general probabilistic model of cell inactivation proposed by Judas and Lokajíček (2001), which enables one to respect even the detailed sructure of cell survival curves. Problems of corresponding numerical calculation are discused in details.
On the use of accelerated hadrons in treatment of cancer
Kundrát, Pavel ; Lokajíček st., Miloš
Basic principles of hadron radiotherpy and its current use worldwide will be summarized. Situation in the Czech Republic will be discussed, too
Mathematical moddeling of radiobiological mechanism in cells
Lokajíček st., Miloš ; Kundrát, Pavel
A mathematical model will be presented thet enables to correlate the inactivation effect of defined numbers of ionizing particles traversing cell nuclei with corresponding cell survival curves. Applications of the given model in analyzing the relative biological efficiency of protons and ions in their Bragg peak regions will be discussed
