Measurement of bulk etch rate of CR-39 with atomic force microscopy

Study of DNA integrity in alpha-particle radiobiological experiments using thin CR-39 detectors

“…The alpha source employed in the present study was a planar 241 Am source (main alpha energy = 5.49 MeV under vacuum) with an activity of 4.26 kBq. After irradiation, the bottom side of the cell dishes was etched by 14 N KOH solution at 37 • C (corresponding to a bulk etch rate of 0.64 ± 0.01 m/h determined by the masking method, Ho et al, 2003;Yasuda et al, 1998) for 3 h 40 min to reveal the tracks. These tracks were used as markers for alignment only, and are referred to as "base tracks".…”

Simple preparation of thin CR-39 detectors for alpha-particle radiobiological experiments

“…The bulk etch rate of the CR-39 SSNTDs was measured by the masking method [5,6]. CR-39 SSNTDs of dimensions 1 · 1 · 0.1 cm (thickness) were prepared.…”

Feasibility study on the use of polyallyldiglycol-carbonate cell dishes in TUNEL assay for alpha particle radiobiological experiments

“…After irradiated by the 1 MeV alpha particles, the bottom side of the cell dishes was etched by 14 N KOH solution at 37°C (corresponding to a bulk etch rate of 0.64 ± 0.01 lm/h determined by the masking method [13,14]) for 3 h 40 min. Such a low-etching temperature was chosen to prevent the epoxy from being dissolved in the strong etchant at high-temperatures.…”
