background: medical x-rays are the largest man-made source of public exposure to ionizing radiation. it is important to avoid conditions where the amount of radiation used is more than that needed for the procedure. materials and methods: the entrance skin exposure (ese) measurement was conducted for quality control of x-ray machines and survey of operator’s experimental techniques. the eses we...

The supposition that X-ray would affect the developing and the developed verruga nodules experimentally induced in the monkey, has proved correct. The experiments show that the early verruga nodules when exposed to a single, properly graduated dose of X-ray producing merely erythema of the skin, are inhibited in their evolution. Moreover, the skin of Macacus rhesus monkeys is modified by a sing...
