Theoretical and experimental study of the CR-39 behavior under electron beam

Le rôle des simulations numériques Monte Carlo dans les domaines associés à la physique des rayonnements ionisants

“…Ainsi, avec le C2M, les simulations Monte Carlo ont permis à la fois de mieux contrôler, à l'échelle du µm, le comportement du CR-39 sous irradiation électronique en tant que guide optique (Isabey et al, 1999) et d'étudier les modifications topographiques du polymère PADC (Fig. 6, Taupiac-Darraud et al, 2000).…”

Use of Cr-39 Polymer for Radiation Dosimetry

“…Irradiation of polymeric substances by high energy ionizing radiation such as x-rays or gamma rays causes many changes in the polymer. It may degrade polymeric materials by random fracture of the main chain with the number of fractures being proportional to the radiation dose [9][10][11][12]. The bond breaking may give rise to free radicals [9,11] , ionic species, water molecules, gaseous products, etc.…”

“…The bond breaking may give rise to free radicals [9,11] , ionic species, water molecules, gaseous products, etc. [10,11,13] . It has been reported that Co 2 molecules are produced in irradiated CR-39 plastic by gamma ray (or x-ray) and the production of Co 2 was attributed to bond breaking in the CR-39 plastic by radiation [3,10,11,14] .…”

“…It has been reported that Co 2 molecules are produced in irradiated CR-39 plastic by gamma ray (or x-ray) and the production of Co 2 was attributed to bond breaking in the CR-39 plastic by radiation [3,10,11,14] . This Co 2 is trapped inside, this can lead to the subsequent crazing and cracking of the plastic due to accumulated local stress [11,14] . The production of Co 2 is a function of gamma ray dose [11,15] .…”
