radiological conditions to change. There are two general
categories of measurement used for external exposure
associateed with uranium, portable survey instruments and
personnel dosimeters.
Gamma radiation from uranium is normally not the
controlling problem. For example, the contact beta
radiation field from depleted uranium is approximately 240
millirem per hour, while the contact gamma radiation field
is less than 10 millirem per hour. However, significant
gamma fields can exist in areas where large quantities of
uranium are stored, such as a storage area for uranium
contaminated soil. The accuracy and precision of survey
instruments used for measurement of beta radiation fields
depend on many factors which must be addressed, such as
energy response and geometry factors. Accordingly, these
surveys are typically conducted by Radiological Control
personnel. Neutron fields from enriched uranium fluoride
compounds can also add to this area of concern. Depending
on the magnitude of neutron fields generated, periodic
neutron dose rate measurements are made, typically by
Radiological Control personnel.

thermoluminescent dosimeters, used in most DOE uranium
facilities, provides the most accurate and precise means of
measuring doses received by workers.
