Abstract
IT has been generally considered, on the basis of the work reported by Hendricks and Dean1, that a sufficient margin of safety exists in the tolerance of the plant to radioactivity to permit the use of phosphorus-32 as a tracer in phosphate experiments without fear of any effects on plant growth from the radioactive isotope. The recent communication by Scott Russell and Martin2, indicating an injurious effect, suggests that a danger exists which requires further study.
