Aim: In this work we present a methodology to produce an ?imprint? of cells cultivated on a polycarbonate detector by exposure of the detector to UV C radiation.Background: The distribution and concentration of10B atoms in tissue samples coming from

A standard material with a known amount of 10B has to be used as a reference for a quantitative evaluation of boron concentration in autoradiography images of tissue samples. However, the yield of detected charged particles is conditioned upon certai

The determination of the local concentration of boron in the different regions of tissue samples treated by Boron Neutron Capture Therapy (BNCT) could be made through the evaluation of the number of tracks forming autoradiography images. It is necess

A device consisting of poly allyl diglycol carbonate (PADC) foils with a polyethylene and polyvinyl chloride (PVC) radiator was calibrated in order to perform the dosimetry of an 241Am-Be source covering a dose range from 0 to 3.1 mSv. Working condit

The folding track replica method is applied to study the amorphous SiO 2 layer of Si – SiO 2 wafers irradiated with beams of 118 MeV Au 197 and 80 and 106 MeV I 127 ions. This technique is used to evaluate single track profiles. Measurements of the

When some irradiated polymer detectors are analysed at submicroscopic level, four zones can be distinguished in the damaged region surrounding the ion trajectory: core, halo, cross-linking and bulk. The folding track replica technique has been used i

Ion tracks shape, in irradiated and etched crystalline detectors, is ruled mainly by the material structure. Abundant data of rhombic tracks in muscovite mica etched with HF under several conditions are reported in the literature. In the present pape

Several authors reported data showing a differentiated structure of ion tracks in some polymers, when analysed at submicroscopic level. Four zones can be distinguished: core, halo, cross-linking and bulk, at least in tracks produced by ions with spec

External proton and 6,7 Li beams, of energies around 24 and 48 MeV respectively, were produced and characterized dosimetrically at the Tandem accelerator TANDAR in Buenos Aires and used for radiobiology studies on tumor and normal cell cultures. The

The liquid drop model (LDM) was developed to perform radiation damage studies in metals in an ionic energy range where molecular dynamics cannot be used because of computational restraints. In this work, the model is extended in an effort to explain
