Embodiment Construction

[0022]The present invention offers a solution to the problem of providing accurate simulated dosimetry to nuclear facility training programs by using a real-time-location-systems (RTLS) in combination with a radiation exposure model. The RTLS may employ near-field electromagnetic ranging (NFER) technology, ultrawideband (UWB), time difference of arrival (TDOA), time-of-flight (ToF) or any other RTLS technology known by practitioners of the RF arts.

[0023]FIG. 1 illustrates an exemplary simulated dosimetry system 100 in accordance with the present invention. Referring to FIG. 1, a training facility 108 may include any number of different types of hardware as are necessary to provide the necessary training. Included in the training may be exercises directed to handling fault conditions including leaks or spills of radioactive materials. Such fault conditions may be modeled by computer 124 as set up by a trainer / operator. Multiple functions are shown performed by computer 124; however, ...

Abstract

A system for providing a simulated total dose exposure measurement during a nuclear facility training exercise by locating participants using a real time location system, modeling incremental exposure as a function of location and summing incremental exposure to produce a total dose for each of the participants. Total dose may be displayed via a wireless link to a simulated dosimiter worn by each participant. Radiation sources may also have location tags and the exposure model may be modified in real time according to the tracked location of the radiation source. In one embodiment, the locating technology comprises near field locating technology based on comparing near field signal characteristics. Alternative locating technologies may be used.

Description

RELATED APPLICATIONS[0001]This application claims the benefit under 35 USC 119(e) of provisional application Ser. No. 60 / 841,598, titled: “System and Method of Simulated Dosimetry Using a Real Time Locating System,” filed Aug. 31, 2006, by Schantz, which is hereby incorporated herein by reference in its entirety.BACKGROUND[0002]1. Field of the Invention[0003]The present invention pertains generally to the field of real time simulation based training systems, more particularly to training systems for workers in nuclear or other hazardous environments.[0004]2. Background of the Invention[0005]Radiation exposure of workers in the nuclear industry poses a significant safety and health hazard to the workers, and imposes significant costs to the utilities that employ them. Training is essential to help workers avoid unnecessary exposure to radiation hazards and minimize total dosage.[0006]Existing training techniques involve equipping workers with simulated dosimeters during training exer...
