A radiation detecting device includes a radiation detector and a supporter. The radiation detector includes a substrate that has flexibility and a semiconductor element formed on an imaging surface of the substrate. The supporter is formed of foam and supports the radiation detector.

A radiotherapy dose rate monitor system includes an electrode configured to be impinged by radiotherapy radiation, and a current measurement circuit configured to measure a current through the electrode. An emission of secondary electrons emitted from the electrode provides a majority of current through the electrode.

A method of monitoring a radiation dose includes impinging an electrode with radiation and measuring a current through the electrode. Emission of secondary electrons emitted from the electrode provides a majority of the current.

A method for measuring radiotherapy doses on a subject undergoing radiotherapy or other treatments with ionizing radiations includes: electrically insulating the subject during the radiotherapy treatment; applying at least one electrode to the subject, or connected to an amplifier with a system for acquiring the signal outgoing from the amplifier; detecting, by means of the at least one electrode, the voltage pulse produced during the radiotherapy treatment and deriving from the ionization secondary electrons set into motion and/or by the loaded net charge induced in the subject; converting said voltage pulse into a value of charge induced by the treatment in the subject; and determining the dose of ionizing radiations received by the subject by a processing system which uses the above value of the induced charge, the energy spectrum of the incident beam and the contact surface of the incident beam on the subject.

A direct ion storage (DIS) radiation detector or dosimeter has a design that is easy and low cost to manufacture using semiconductor processing techniques. The detectors include internal communications interfaces so they are easy to read. Different interfaces, including wired, e.g. USB ports, and wireless interfaces, may be used, so that the dosimeters may be read over the internet. The detectors can thus be deployed or used in a variety of detection systems and screening methods, including periodic or single time screening of people, objects, or containers at a location by means of affixed dosimeters; screening of objects, containers or people at a series of locations by means of affixed dosimeters, and surveillance of an area by monitoring moving dosimeters affixed to people or vehicles.
