Abstract
Certain embodiments of the present invention provide a system and method for predicting long-term exposure to a hazardous environment based on a user-controllable measurement interval of short duration. In an embodiment, the system includes an electronic circuit for receiving one or more signals representative of the level of a hazard in an environment using one or more of a hazard level sensor and a direct input jack. The system further includes a processor within the electronic circuit for determining an accumulated dose over a user-controllable measurement interval. In addition, the processor predicts hazardous exposure for a user-settable extended period greater than the user-controllable measurement interval and based on the accumulated dose. The dosimeter also includes a user-operable switch within the electronic circuit and in communication with the processor for controlling the user-controllable measurement interval to be less than a nominal measurement interval.
