Dysprosium is one of a number of materials that could be used as a burnable poison, for at least one of its isotopes has a neutron absorption cross- section that is greater than the fission cross-section of U/sup 235/. The information available to date on this element is considerably less extensive than on most elements. This memo gives a summary of our present cross-section knowledge on Dy and an estimate of the uncertainties therein. It is impossible to conclude from what we now know whether or not Dy has the nuclear properties requisite to be a successful burnable poison. Two experiments to elucidate the situation are suggested.
