Effect of environmental conditions such as humidity during irradiation, or during post irradiation storage and different light conditions on the response of locally manufactured 3 mm thick clear PMMA dosimeter were investigated. The dosimeter showed a uniform response at almost all humidity conditions (12-92%) during irradiation. The response during post irradiation storage at different humidities also showed a stable response at least for two weeks after irradiation at almost all humidity conditions (12-92%); however at longer storage time fading takes place.
