BODIPY based fluorescent dosimeter for gamma radiation

Accurate measurement of gamma (γ) doses is highly important to avoid any damage to human being and the materials used for γ-exposure. Although various γ-detectors such as ionization chambers, scintillators, thermoluminescent and semiconductor detectors etc are available but many of these techniques are highly costly with several limitations. Thus, it is extremely desirable to develop highly sensitive, low cost and easy to use γ-dosimeter for practical uses. Fluorescence sensors are highly popular due to their high sensitivity, selectivity, low cost, easy operation etc. But fluorescence sensor for γ-radiation is rarely explored. Here, we report a highly sensitive fluorescent γ-dosimeter based on anilino-BODIPY dye
