The roots of Zea mays seedlings were exposed to ultrasonic radiations (1 MHz) of intensities in the range of 0-1-0-8 W cm-2 (pulsed or continuous modes) for times between 2 and 60 min, together with an X-ray dose of 775 rad which was given before, after or simultaneously with the ultrasound. These experiments have shown that ultrasound and X-rays seem to act independently of each other, suggesting that the mechanism of damage due to X-rays is different from that due to ultrasound. An increase in the X-ray effectiveness under the action of ultrasound, as reported by various authors who worked with different tissues, has not been found.
将玉米幼苗的根暴露于强度范围为0 - 1至0 - 8 W/cm²的超声波辐射（1 MHz）下2至60分钟（脉冲或连续模式），同时给予775拉德的X射线剂量，该剂量在超声处理之前、之后或与超声同时给予。这些实验表明，超声和X射线似乎相互独立起作用，这表明X射线造成损伤的机制与超声造成损伤的机制不同。未发现如其他研究不同组织的作者所报道的在超声作用下X射线有效性增加的情况。
