Dose history summary request form

The National Dose Registry will release a Personal Dose History Summary (PDHS) upon request. Employers and prospective employers can obtain an Employee's Dose History Summary (EDHS) upon written consent of the radiation worker.

A Dose History Summary (DHS) request form can be printed from this site. Dose records on a DHS are grouped by dose type, year, and employer.

Routine DHS requests are usually processed within 10 working days. Please refer to instructions sheets for more detailed information on how to submit a DHS request to the NDR.
