Radon detector SISIE + scintillation cells

SISIE is a new version of LUK devices with a new sample changer, a better design, a more sophisticated software and other improvements. Glass type Lucas cells (volume 125 ml) produced by RADON v.o.s. are used. The photomultiplier is placed inside the device. The sample changer is not so heavy and it is located above the measuring unit. It has three positions: one for inserting the Lucas cell (inserting position, covered by a removable cap), a "waiting" position (Lucas cell should be kept in the darkness for at least 2 minutes before measurement) and a measuring position. During measurement, the Lucas cell is located above the photomultiplier, not below the photomultiplier as in case of LUK 4E. Taking out of the cell from the changer is easier. Similarly as in case of LUK 4E, two basic measuring modes are available: (a) a counter mode, results are given in pulses; (b) a "Rdn" mode, results are given in kBq/m3. Measurements can be directed using a PC. An electric power supply is required for operation (no batteries available).
