Disclosed is an apparatus for measuring the distribution of radiation dose emitted from a brachytherapy insertion tool, the apparatus including a housing having defined therein a measurement space in which the brachytherapy insertion tool is located, a fluorescent member disposed at the housing, the fluorescent member being configured to react with radiation emitted to the measurement space and to emit light, a camera disposed in the housing, and a cover coupled to one surface of the housing, the cover being configured to cover the fluorescent member. The portion of the fluorescent member to which radiation from a radiation source of the brachytherapy insertion tool is applied reacts with the radiation and generates light, brightness of the light varies depending on distribution of the radiation, and the position at which the light is bright is calculated to measure the direction in which the brachytherapy insertion tool has no shielding.

A radiation dosimeter for measuring radiation dose within a region includes a structure having a scintillating material that emits light when exposed to radiation.

A sensor and a sensing device for determining a radiation dose, a readout device for reading out a sensor, and a method for determining a radiation dose, the sensor (110) comprising: an organic material, the organic material having a radiation dose-dependent light emission characteristic such that a characteristic light emission is generated from the organic material once the organic material has accumulated a radiation dose greater than a threshold radiation dose characteristic (172), the sensor (110) being further configured such that a difference of the threshold radiation dose characteristic (172) and a radiation dose accumulated in the material represents a to-be-determined radiation dose.

A dosimeter for recording a level of radiation exposure, and a reader for measuring the level of radiation recorded by the dosimeter, are disclosed. In some embodiments the dosimeter comprises at least one luminescent bead coupled to a fibre. The reader comprises a means for holding the dosimeter, stimulating means for stimulating a region of the dosimeter to cause luminescence, and a light detector for measuring intensity of light produced by the at least one bead during heating. In some embodiments the reader can be configured to record readings from a dosimeter comprising a fibre without beads. A system comprising the dosimeter and reader is disclosed. Methods of using the dosimeter, reader and system are also disclosed.

Substrates for suspending sample elements are disclosed, as well as sample platforms comprising such substrates, in which the sample elements can be analyzed with improved reliability. In exemplary embodiments, such sample elements are used in thermoluminescence dosimeters (TLDs) or optically stimulated luminescence dosimeters (OSLDs) to provide a calculated radiation dose with improved accuracy. The reproducibility associated with analyzing a sample element, and particularly one suspended by a film or encapsulated within films, may be significantly improved by tensioning the film(s). Tensioning may result during assembly of a sample platform, using a mechanical creasing force that is applied as the result of the configuration of a substrate of the sample platform, such as opposing sections or plates of this substrate. Alternatively, tensioning may be achieved using a separate application of force to the film(s) against a section or plate of the substrate.
