Experience with gamma and BD-100R neutron bubble detectors

After achieving a reasonable success in BD-100R neutron-bubble detectors, the Bubble Technology Industries (Canada) has recently developed a new type of γ-bubble detector and is commercially available. A series of experiments were carried out to determine the sensitivity and the effect of temperature on both of the above mentioned detectors. The response of these detectors is found to be strongly dependent upon the temperature during irradiation. The γ-bubble detector needs a lot of improvements before it can be used in actual measurements. Although BD-100R detector has a lot of promising properties, it cannot replace CR-39 based personnel neutron dosimeters, but they complement each other.
