A method for optimizing an aviation radiation dose comprises a) gathering flight-relevant data including at least one flight schedule; b) gathering radiation data including at least a current radiation field assigned to the at least one flight schedule, historical radiation data assigned to the flight-relevant data and a radiation dose threshold; c) calculating an expected radiation dose based on the flight-relevant data and the radiation data; and d) modifying the flight-relevant data and repeating steps a) to c) at least once in order to obtain optimized flight-relevant data with regard to the expected radiation dose. With each iteration the flight-relevant data is modified.

Embodiments herein disclose systems, methods, and computer-readable media for intelligently monitoring radiation exposure values. The intelligent monitoring can monitor an amount of radiation a clinician is exposed to (via exams already performed) and identify how much radiation is acceptable for continued exposure before exceeding an exposure threshold value within a predetermined time period. Additionally, the system described herein can provide insights into how many procedures of a particular type a clinician is available to complete before expiration of the predetermined time period. The monitoring data can be provided via a graphical user interface and can be integrated into a scheduling system, an electronic health records system, etc., to provide meaningful insights for resource management.

A breakage timing prediction system of a radiation detector includes: a sensor that detects a physical quantity applied to a radiation detector; a first hardware processor that collects information on the physical quantity detected by the sensor and analyses the collected information on the physical quantity to predict a breakage timing of the radiation detector; and a notifier that gives a notification of information on the predicted breakage timing of the radiation detector.

A portable electronic dosimeter is described that comprises a plurality of detectors each configured to detect a type of ionizing radiation, wherein each detector is associated with an amplifier configured to produce an output in response to a plurality of detected photons of the ionizing radiation and an event counter configured to produce one or more counts in response to the detected photons of the ionizing radiation over an integration time; and a processor configured to receive the one or more counts from each of the counters and determine if there is coincidence of the one or more counts of all the detectors, wherein if there is coincidence the processor is configured to provide an over range alarm signal.

A portable detection apparatus can include a housing, a first detector for detecting ionizing radiation from a first subject and a second detector within the housing for the detecting the background radiation. A shield within the housing can surround the first and second detectors and define a shield aperture around the first and second detectors for radiation from the subject to enter the housing. A radiation blocking member can substantially block at least a portion of the ionizing radiation from reaching the second detector, whereby radiation detected by the second detector comprises substantially only the background radiation. A processor module can be connected to the first and second detectors for determining the amount of ionizing radiation detected by the first detector attributable to secondary radiation.

A mobile audio mesh distribution (MAD) system/method allowing synchronized audio distribution to modular audio modules (MAMs) and/or drone delivery aircraft (DDA) in mesh audio network (MAN) is disclosed. The system/method utilizes a computer control system (CCS) that communicates wirelessly using a plurality of RF transceivers (RFT) over a RF mesh network (RMN) with one or more MAM that are configured to independently communicate with each other and automatically determine if audio updates are required from the CCS. The MAM are configured to query other MAMs in the RMN to determine if a connected MAM has updated audio/text (UAT), and if so, to download the UAT and schedule audio playback on a speaker. Messages may be transmitted to the MAM in the event of an emergency, terrorist event, or a physical event detected (PED) using prerecorded or updated audio that trigger immediate or scheduled playback by the MAM.
