Primary and Secondary Identifiers
The goal of external dosimetry data entry is to reproduce the nomenclature used in the hard file such that a researcher can obtain precise quantity definitions from the OCAS Technical Basis documents. The 'Primary Identifier' and 'Detail' fields work hand-in-hand to accomplish this task. If the hard file uses two or more names to describe the type of radiation or dose, the work site's reporting or compliance dose quantity is the preferred primary identifier (if it is known) and secondary identifiers are listed in the 'Details' field. The primary identifier may be determined from the OCAS Technical Basis documents. Some of the terminology reported in the technical basis documents is summarized as historical nomenclature in Table 1 (deep dose) and Table 2 (shallow dose).
Data Entry
-
Examples
- 1. A 6/10/1958 Hanford dosimetry record reports 1.1 rem penetrating whole body external exposure.
-
2. External dosimetry records report a total hand exposure between 6/27/1950 and 5/24/1978 of 0.17 rem.
- Data Entry:
Primary Identifier – Select the primary identifier used in the hard file to describe the type of radiation (or type of dose) from the dropdown list. (For examples 1 and 2: select whole body, since it was the Hanford's compliance dose quantity in 1958, and extremity respectively.)
Details – List any secondary identifiers used in the hard file to identify the type of radiation (or type of dose). (For examples 1 and 2: enter "penetrating," since it was also used to describe the external exposure, and "hand" respectively.)
Monitoring Period – Select the external monitoring period from the dropdown list: Interval - single external measurement; Annual Sum - sum of all external measurments taken during a calendar year; Cumulative - sum of all external measurements taken from start of employment to date of exposure report; Lifetime - sum of all external measurements taken from hire to termination of employment. Lifetime external doses sum all exposures from all employers.
Dose Quantity – Select the type of external quantity – absorbed dose, dose equivalent, or exposure – from the dropdown list.
Start Date/Time – Enter the beginning of the measured external "exposure" period. If the exposure period is reported on a weekly or quarterly basis without mentioning specific start and end times, enter default start/end times. (Exposure is being used loosely here as it refers to all types of radiation: gamma, neutron, beta, x-ray, etc.)
End Date/Time – Enter the end of the measured external "exposure" period. If the exposure period is reported on a weekly or quarterly basis without mentioning specific start and end times, enter default start/end times. (Exposure is being used loosely here as it refers to all types of radiation: gamma, neutron, beta, x-ray, etc.)
Reported Value – Enter external measurement as it appears in the hard file (do not perform unit conversions).
Reported Uncert – Enter the uncertainty on the external measurement as it appears in the hard file (do not perform unit conversions).
Reported Unit – Select the unit used to report the external measurement and uncertainty in the hard file.
Detector Type – Specify the type of detector used, if known.
Comments – Enter any additional external monitoring information here.
Source – Enter the source of external monitoring data as: document date – document name (i.e. 5/22/79 - internal dosimetry memorandum from site health physicist). Do not include specific personnel or registrant names.
