Abstract:
1. A personal radiation monitor, comprising: a processor responsive to a radiation detector; said radiation detector configured to produce real time radiation exposure data; said processor configured for calculating one or more characteristics of an individual's radiation exposure; said processor further configured to continuously recalculate said radiation exposure data to update the one or more radiation exposure characteristics; and a display responsive to information provided by said processor, said display adapted to display at least one of said or more radiation exposure characteristics as a primary signal from said processor; said processor further configured to transmit a secondary signal to said individual; said secondary signal correlating to a range of values of one of said one or more radiation exposure characteristics; wherein said one or more radiation exposure characteristics further comprise a stay time based on the individual's maximum permissible radiation dose limit, said processor further configured for continuously recalculating said stay time to accommodate for the accumulative exposure level or changing radiation dose rates; wherein said processor is configured to output said stay time to the display at a display time interval; and wherein said display time interval locks the value of the display for a specified period of time.
