Smart fire hydrants

A smart module configured for monitoring a fire hydrant, said smart monitor module comprising:

• an operating-nut-extension defining a module-nut at a first end and a nut-receiver at an opposing second end wherein said module-nut and said nut-receiver are separated by an extension-section and wherein said nut-receiver is configured for being mechanically associated with a fire hydrant with a plurality of output ports and wherein said turn on nut is configured to control the flow of a flow of a fluid to said plurality of output ports so that rotating said module-nut rotates said fire hydrant turn on nut thereby providing fluid to all of the fire hydrant output ports;
• a housing disposed between said first end and said second end and at least partially surrounding said extension-section;
• a processing device disposed within said housing wherein said processing device is associated with a memory that is at least one of (a) integral memory and (b) external memory, wherein said memory is configured for storing at least one of radiation-threshold-data and warning-criteria-data;
• an ionizing radiation sensor electrically associated with said processing device, said radiation sensor configured to generate a radiation-signal reflective of ionizing radiation striking said radiation sensor, and wherein said processing device is configured to use said radiation-signal and said radiation-threshold-data to generate radiation-status-data;
• a transmitter electrically associated with said processing device;
• a power source disposed within said housing and electrically associated with at least one of said processing device, said radiation sensor, and said transmitter;
• and
• wherein said processing device is further configured to transmit a data-signal comprising at least part of radiation-status-data.
