1. A monitoring system for detecting environmental conditions, comprising:

  • a sensing unit including one or more sensors for obtaining data related to environmental conditions, the one or more sensors including at least one ofa radiation sensor, andfirst and second orthogonal chemical sensors that use dissimilar technologies to detect a chemical at dissimilar detection thresholds;

    an air pump for providing air flow to at least one of the one or more sensors;

    a controller interfaced with the sensing unit for receiving, interpreting and encoding the data related to environmental conditions into a predetermined format,wherein the controller determines whether to encode an alarm condition into the data in a predetermined format based onwhether the first and the second chemical sensors both detect the chemical, andwhether the first and second chemical sensors each detect the chemical for a predetermined duration of time; and

    a communication device including a display for receiving the data in a predetermined format from the controller, including the alarm condition, if present, forming an e-mail message and transmitting the e-mail message including the data in a predetermined format to at least one predetermined e-mail address.
