The monitoring period for the badge (monthly or quarterly) was not known to the State. Investigation has determined that the researcher is believed to have worked only with P-32 and has done nothing out of the ordinary. The lab area where the researcher worked has been surveyed and there is no indication of contamination. The researcher is currently having blood work done to determine if there is any indication of radiation damage. The licensee is also working with Landauer focusing on the discrepancy between the deep dose and shallow dose readings on the badge. For an overexposure of this magnitude, it would be expected that the shallow dose would be much greater than the deep dose. The University Radiation Committee is leading the investigation for the licensee. The State plans to evaluate the results of the licensee's investigation findings before considering what actions it will take .
