Resumodose at the rate of 104 rads/min or higher and located in an occupied laboratory. This can be done with very low-energy X-rays (Grenz rays). Although protection is relatively easy, the rapid absorption of such a beam in very thin layers of material presents a problem in calibration and makes difficult the uniform irradiation of thick samples. The dose uniformity is improved by irradiating the sample twice, once from each side or by using two tubes simultaneously. A description is given of an X-ray unit of the latter type. The irradiation and calibration techniques are described, and a statement of the limits to the dose homogeneity is given.
