Occasional x-rays as required by the child’s condition and as prescribed by the doctor will generally not have a significant effect on the body, but repeated prolonged x-rays may affect the development of the child’s gonads, for example. X-rays have a certain amount of radiation, but due to the condition of the need for occasional X-rays, the body of the child basically will not have serious harm. Because the dose of radiation from a single X-ray is small, as long as it is not repeated for a short period of time, it basically will not affect the growth and development of a small child. However, if the X-ray is repeated, or if the duration of a single X-ray is too long, the gonadal development of small children may be affected, and symptoms such as developmental abnormalities may occur. It is advisable to consult a medical professional as to whether or not X-rays are necessary for small children.
