Date Jan. 7, 1982.Dosimetric data are registered in several channels as a directly readable bar chart, the height of the readable registration of each respective bar being a direct measure of the integrated dose value of the associated channel. Preferably, the registration is made by means of a measurement signal transducer (1) and a measurement interval separator (3) connected thereto, the separator controlling a number of parallel registration channels, each of the channels including a LED (10-13), a film (28) for integrating registration of radiation emitted by the LED, a slot-shaped aperture opening (34-37) for providing a bar-shaped incidence of radiation flow on the film, and a wedgy grey filter (30-33) attanuating the radiation intensity of the flow striking the film stepwise or continuously in the direction of the bar. |
