Units
The following properties are currently available within the database and are based upon data currently entered. The user can select from this list of properties when using the custom form in the database. In order to maintain maximum flexibility not every volume contains every property. Unless specified, units of measurement are different for different volumes and will be able to be changed via the use of a 'unit conversion matrix'. At the present time a unit conversion matrix has been specified for conversion between different irradiation doses. As Access 97 allows descriptive field names, properties should be self-explanatory.
