Abstract: A dynamic, wearable low-cost, personal high-sensitivity and wide-dynamic range measurement apparatus and method provide an accurate, objective and independent device for the real-time measurement and monitoring of an individual's career or lifetime exposure to known and unknown sources of harmful ionizing radiation, for real-time radiation exposure monitoring, overexposure warning and cancer risk management due to harmful radiation in all ambient environments.

Abstract: A portable measurement apparatus and method for independent in situ analysis of emitted radiation, the patient or subject's total radiological dosage and spectral component levels of radiation for a specific radiation emission machine is disclosed. Said apparatus uses a plurality of electromagnetic emission detectors as a means to separate and analyze the electromagnetic spectral output signals emitted by an individual X-ray, CT, MRI, PET, metal detecting, or foreign object screening machine, etc., into key radiological component intensities.

Abstract: A hand held measurement apparatus and method for in situ optical analysis of a specific display screen or viewing box and associated ambient light environment is disclosed. The apparatus uses a plurality of input collector optics and a plurality of optical filter/photodetectors as a device to separate the light output of an individual monitor screen, display screen, or viewing box and associated ambient light environment into key optical component intensities, the analysis of which are used to optimize the probability for a correct diagnosis by a qualified viewer/analyst. The optical signals are converted into digital electrical signals, processed, and compared to previously stored information of the specific viewing display and the viewing display environment in order to determine if the combination of viewing device and viewing environment is either GO (acceptable, in compliance) or NO GO (not acceptable, non-compliant) according to industry standards or approved procedures.

Abstract: A device for measuring light from a source includes a photometer and a collector. The photometer may include a detector, circuitry for processing output signals from the detector, and an output such as an LCD display. The collector engages with the photometer such that light from the source is incident on the detector and ambient light is prevented from entering. The collector may be configured to be releasably engageable with the photometer. A plurality of interchangeable collectors may be provided so that a single photometer is enabled to measure light from a plurality of sources. The collector may include a hood for engaging the source to block ambient light. The collector may also include optics disposed within the hood for directing light from the source onto the detector. The optics may include an optical diffuser disposed within the hood such that light from the source first passes through the diffuser to be incident on the detector.
