- Ergonomically engineered for easy handling in clinical situations
ORTEC’s Model AWM-1 Actinide Wound Monitor is designed to accurately locate actinides embedded in body tissue, so that they may be removed surgically. The instrument’s design is based on specific suggestions from a leading radioisotope fabricating and reprocessing facility.
Energy Resolution and Position Information
The instrument contains a rugged, reliable, 6-mm diameter, 5-mm deep HPGe planar detector which provides excellent energy resolution and position information. By using Ge rather than Si, the ratios of intensities of the gamma-ray lines can be compared to those of the L x-rays (13 to 17 keV) to obtain information on the depth of the actinides.
The ergonomic design of the instrument ensures optimum convenience in clinical situations. The construction and placement of the handle permit the user to operate the instrument for extended periods of time with little hand or arm fatigue. The one-hour supply of liquid nitrogen in the 0.06-liter dewar provides ample time for completion of most clinical procedures.
Personnel Safety and Equipment Protection
Safety of the patient and the operator is assured by an all-attitude dewar. Liquid nitrogen cannot be released from the dewar regardless of its orientation. A red LED on the top of the instruments warns if the radiation level being measured is high enough to drive the preamplifier out of its linear range. If the liquid nitrogen supply is exhausted while the detector is operational, an internal sensor cuts off the high voltage supply to protect the instrument from damage.
A special 25-liter storage fill dewar supplied with the AWM-1 keeps the instrument filled with liquid nitrogen and ready to use.
