in vivo
The In Vivo tab contains data associated with in vivo (external) measurements (click image to enlarge).

Field Descriptions

A complete listing of in vivo fields follows. Many of the fields appear only on the data entry forms. For example, reported activities exist on data entry forms, but only the derived (standardized) activities are displayed on data viewing forms.

Monitoring Target

'Monitoring Target' stores the name of the organ or part of the body that the in vivo count was trying to measure (i.e. the monitoring target for a skull or tibia count might be the skeleton).

Detector Position

'Detector Position' stores a description of where the detector was positioned on the body (i.e. the Am content of the skeleton might be measured by positioning the detector over the skull or kneecap).

Contaminant(s)

'Contaminant(s)' stores the contaminant (radionuclide or type of radiation) or mixture measured by the in vivo count.

Measured Directly?

'Measured Directly?' indicates whether the activity of a radionuclide was measured directly (using a chemical separation, energy bins, etc) or measured indirectly (e.g. by recording gross alpha as Pu or calculating Pu activity from Am result).

Count Start Time

'Count Start Time' stores the time that the in vivo count was started.

Reported Results: Value

'Reported Results: Value' stores the measured activity as reported in the hard file (using the same unit as in the hard file).

Reported Results: Uncert

'Reported Results: Uncert' stores the uncertainty in the measured activity as reported in the hard file (using the same unit as in the hard file).

Reported Results: MDA

'Reported Results: MDA' stores the minimum detectable activity as reported in the hard file (using the same unit as in the hard file). This value is also sometimes based upon the MDA reported in the OCAS technical basis documents.

Reported Results: DL

'Reported Results: DL' stores the decision level as reported in the hard file (using the same unit as the hard file).

Reported Results: Unit

'Reported Results: Unit' stores the unit used in the hard file to report the measured activity, uncertainty, MDA, and DL.

<MDA

The '<MDA' checkbox is checked if the hard file reports that an in vitro sample's activity was less than the minimum detectable activity. This checkbox can also be based upon the MDA reported in the OCAS technical basis documents.

Derived Value: Activity

'Derived Activity: Value' stores the standardized activity, which is calculated by converting the reported activity to the standardized unit: pCi, cpm, or ug.

Derived Value: Uncert

'Derived Activity: Uncert' stores the uncertainty in the standardized activity, which is calculated by propagating the reported uncertainty into the standardized unit: of pCi, cpm, or µg.

Derived Value: MDA

'Derived Activity: MDA' stores the standardized minimum detectable activity, which is calculated by converting the reported minimum detectable activity into the standardized uni: pCi, cpm, or µg.

Derived Value: DL

'Derived Activity: DL' stores the standardized decision level, which is calculated by converting the reported decision level into the standardized unit: pCi, cpm, or µg.

Derived Value: Unit

'Derived Value: Unit' stores the standardized unit used to quantify the Activity, Uncertainty, MDA and DL. Standardized units are pCi for activity, cpm for counts, and µg mass is used to quantify the activity.

Count Length

'Count Length' stores the length of the in vivo count.

Comments

'Comments' contains any additional information that is pertinent to the in vivo record.

Laboratory/Detector

'Laboratory' contains the name of the laboratory where the in vivo sample was analyzed and/or the detector(s) used.

Source

'Source' contains the source of in vivo data – document name and date – in order to expedite access to original hard file documents.

Initials

The 'Initials' field stores the initials of the person who added the in vivo record to the database.

Entry Date

The 'Entry Date' field stores the date that the in vivo record was added to the database.
