Basic information to be secured on claims involving exposure to ionizing
radiation:
1. Precise descriptions of employee’s work assignments, including
particularly, the equipment and appliances subjecting employee to
radiation exposure and the length of time he worked with or was exposed
to each, covering both his exposure in the employment here involved as
WELL AS ALL PRIOR EXPOSURES.
2, Whether there were any uncontrolled exposure incidents and the
extent of all radiation exposures. If feasible, submit scale drawings of the
work areas showing ventilation system, storage facilities or sources of
radiation, X-ray equipment, and the location of any radiation therapy
areas. The shielding at the radiation sources and at the employee's work
place should be described fully.
3. The standard operating procedures used for the storage, issuing,
wearing, collection, developing, and recording of film badge records and
breath samples, and specifying the calibrations of the instruments used.
The same information should be furnished relating to any pocket

ionization chamber records, if such records were maintained by the
employing establishment. {f specific data are not available, a summary of
the results may be submitted.
4. Readings of any continuous monitoring equipment maintained in
the employee’s work area for the period of his employment, with a
description of the equipment, its location, and its position in relation to
the employee’s work area for the period of his employment, and any other
records of survey or tests of radiation made in the employee’s work area.
Please submit copies of reports showing film badge readings, and readings
on dosimeters or pocket ionization chambers. If they have been retired to
storage, please obtain their return as soon as possible and furnish full
information. If no such records are now available please so state.
5. The identification of the persons who recorded and interpreted the
data and their qualifications and training.
6, Complete hospital and/or medical records of all hospitalizations of
the employee, either prior or current, not previously submitted to the
Bureau, including any blood, urine, serological and radiological tests made.
This should include any and alt quantitative information relating to the
level of excreted internally deposited isotopes, results of breath analysis
for radon (where indicated), and whole body counts done during any
period of such hospital or medical care.
