Elucidation of the Two-Step Damage Formation Process of Latent Tracks in Poly(allyl diglycol carbonate), PADC: Role of Secondary Low-Energy Electrons

Abstract

The aim of the present study is to evaluate the mechanisms by which secondary electrons of low energy degrade poly(allyl diglycol carbonate) (PADC) when it is used as a Solid State Nuclear Track Detector. We measured by time of flight mass

Role of intermediate species in the formation of ion tracks in PADC: A review

“…Such an assertion is in line with recent analyses based on IR spectroscopy analyses of irradiated PADC and low energy electron stimulated desorption [112,113]. includes decomposition of the polymer (the detailed description of the decomposition of (A) is in Figure 7).…”

“…Lastly, the present overview didn't include a quantitative description of some processes which are likely to take place in irradiated PADC, namely dissociation into various pairs, ion pair formation and dissociative electron attachment (respectively 3, 4, 6, 7, 8 and 9 in Figure 2). Experiments aiming at shedding some new light on those particular processes have at least in part be started recently [113].…”

Revealing the mechanism of damage to the carbonate ester in PADC polymeric nuclear track detector using low-energy electron stimulated desorption

“…Within the energy resolution of this experiment, this threshold is similar to the onset energy of the DEA resonance for DGMEA. 21 The conversion of DGMEA into its new form that produces an enhanced O À signal reaches its maximum value by B25 eV and remains relatively constant up to 45 eV. Noteworthy here, the increase of O À yield is confirmed even below 15 eV.…”

Estimation of biological effect of Cu-64 radiopharmaceuticals with Geant4-DNA simulation

“…This fact indicates that it is not possible to universally describe the yield of DNA damage and surviving fraction of cells by LET and absorbed dose only. We should focus on the number of interactions with a molecular unit of DNA, including roles played by LEEs, to elucidate the mechanisms of cell killings 57 , 58 . The large RBE of Cu-64 demonstrates the effect of LEE impacts on DNA molecules.…”
