چکیده انگلیسی
Here we report the use of x-ray tube based irradiators as alternatives to gamma sources for laboratory scale irradiation. Irradiators were designed with sample placement in closest possible proximity to the source, allowing high dose rates for small samples. Designs using 1000Â W x-ray tubes in single tube, double tube, and four tube configurations are described, as well as various cabinet construction techniques. Relatively high dose rates were achieved for small samples, demonstrating feasibility for laboratory based irradiators for research purposes. Dose rates of 9.76, 5.45, and 1.7Â Gy/min/tube were measured at the center of a 12.7Â cm container of instant rice at 100Â keV, 70Â keV, and 40Â keV, respectively. Dose uniformity varies dramatically as the distance from source to container. For 2.54Â cm diameter sample containers containing adult Navel Orangeworm, dose rates of 50-60Â Gy/min were measured in the four tube system.
