At large public activities, such as sporting events, races, concerts, and political rallies, protection against chemical and radioactive threats requires a multi-level wireless area, portable, and survey detection approach. Whether the threat is malicious or accidental, for example a broken propane tank pipe or trucks idling in a confined space, the danger is just as real. RAE Systems gas and radiation monitors provide real-time area monitoring with wireless connectivity, as well as portable detection for personnel. Data can be sent to a remote command center or other teams, remediation experts, and public safety leaders for access using a PC, smartphone, or tablet. Since response teams may be from different locations and under different commands, RAE Systems products can interconnect with third-party devices and networks to provide a comprehensive view of potential threats.
