Records Associated With Bioassay Measurements

DOE-STD-1121-98

possible due to resource or data limitations. In such cases, all available dose and intake data should be

maintained in an individual's records.

9.7 RECORDS ASSOCIATED WITH BIOASSAY MEASUREMENTS AND THEIR

INTERPRETATION

Guidance on the type and extent of records associated with both in vivo and in vitro bioassay

measurements can be found in American National Standard "Practice for Occupational Radiation

Exposure Records System" (HPS 1999c).

9.8 DOCUMENTING, RECORDING, AND RETAINING OF PAEC, PAEE, INTAKE, AND

HE,50 FROM RADON AND THORON

Since radon quantities and units differ from the traditional activity concentration (expressed in

:Ci/cm3) and intake (expressed in :Ci), records for exposures and doses from radon, thoron, and their

short-lived decay products will be different. Record should include

radon concentrations, if measured (pCi/L may be used for the time being, but units must be

specified, never assumed)

the value of FRn (if applicable) and whether it is assumed or measured

worker exposure times or stay times (hours)

assigned protection factors (APF) for respirators, if any

potential alpha energy concentration, PAEC (WL)

potential alpha energy exposure, PAEE (WLM)

radon and thoron progeny intake, I, in J

dose conversion factors (rems/WLM; these may change in the future)

HE,50 and Hlung, 50.

Each exposed worker must be unambiguously associated with the air sample result that represents his or

her exposure, including the flow rate, filter type, start time, stop time, and date(s) of operation.

Calibration records for and the identities of active air samplers used for personnel monitoring must

be accessible. Radiological work permits (RWPs) may be a convenient way to record this information.

Archived procedure manuals must specify instructions for operation of active air samplers and the types

of filters that are acceptable for use.
