Abstract:
A hand-carried device (10) for measuring UV-radiation is provided with a radiation filter (13), a sensor (12) and with a signal processing portion between the sensor and a digital read-out unit (31). To ensure that, with such a hand-carried device for measuring radiation, only a single part of the measurement device has to be handled, and that as is customary the read-out unit can be read easily in any measurement position, it is envisaged that the sensor (12) is located together with the signal processing part and the digital read-out unit (31) in a joint housing (26) and that a position-dependent switch is provided together with a switchable coding circuit, by which the digital read-out unit (31) can be controlled in such a manner that it is legible in a position which is rotated through 180o in relation to its plane.

PROBLEM TO BE SOLVED: To provide a brightness measurement device that permits to obtain a brightness estimation value at a set time in a short measurement time with high accuracy, while enhancing flexibility in the set time.SOLUTION: A brightness measurement device 10 includes: a light receiving part 15; a calculation part 23; and a storage part 22. The brightness measurement device 10 uses a first standard characteristic line P1 and a second standard characteristic line P2 obtained from a standard phosphorescent material Pb excited by a mutually different excitation luminance. A brightness estimation line Bp as a linear expression is stored in the storage part 22 that includes a first sub-brightness point b1 from the first standard characteristic line P1 and a second sub-brightness point b2 from the second standard characteristic line P2, both the first sub-brightness point b1 therefrom and the second sub-brightness point b2 therefrom being able to be represented by a value indicated by a first element based on an afterglow brightness at a first time T1 and a value indicated by a second factor based on an afterglow brightness at a second time T2. The calculation part 23 applies a value represented by the value indicated by the first element based on an afterglow brightness at the first time T1 of a target phosphorescent material Pd to the brightness estimation line Bp to calculate a brightness estimation value CP at the second time T2.
Abstract:
A sterilization system consisting of a mobile emitter, a sensing subsystem and a data logging subsystem is described. The emitter has one or more UV emitting lamps or devices. The sensing system comprises at least one remote UV sensor and at least one door sensor. The door sensor comprises a safety shut off door detector and may contain an emergency stop detector and arming detector to protect people from being exposed to UV energy. The system has a remote control for starting, stopping and setting system parameters which include but are not limited to: treatment time, dosage, room size, room number, unit number, floor, facility name, operator name, operator identification number, password, default dosage values, dosage, and patient identification number. The number of treatments per unit of time can be maximized because of the use of incident light measurement.
Abstract:
A system for non-invasive radiation dosimetry comprises (a) a patch, which upon application conforms itself to the curvature of the surface to which it is attached, that comprises radiation sensitive functional cells which, under the influence of radiation, undergo physical and/or chemical changes that are expressed as a response signal taking the form of a measureable and quantifiable alteration in absorbance of a part of the electromagnetic wave spectrum; (b) a camera system which captures, during the exposure to radiation, the relevant part of the electromagnetic spectrum, emitted in the environment and reflected on the patch, in the form of a digital picture, and, as such, allows quantification of the radiation-modulated patch-light interaction properties; and (c) a software algorithm - running on a control unit - which converts the digital picture into an estimate of the dose the patch was exposed to.
