To the Editor.—
We note with interest the growing outcry against mass X-ray film screening. Authorities are concluding that the potential benefit does not warrant the risk of radiation damage.Most analyses of this subject (220:278, 1972) contain a curious, but significant, omission. They do not consider the widely used chiropractic "spinograph." This 14×36 x-ray film of the entire spine is taken routinely by most chiropractors. Depending on technical factors, radiation to the gonads from this procedure is 10 to 1,000 times as great as that from a routine x-ray film of the chest.This procedure should be made illegal. Considering that the spinograph yields little or no diagnostic information, it is remarkable how little publicity its dangers have received.
