An apparatus for arranging at least one sample container inside an optical measuring device includes a carrier for arranging the sample container and a ventilation device. The ventilation device is arranged adjacent to the carrier and is provided with at least one air outlet arranged above the carrier. The ventilation device includes at least one heating element for generating an airflow and heating up the airflow.

Apparatus, device and method for arranging at least one sample container

A method for detecting ionizing radiation with the aid of a scintillation counter and a photomultiplier using an inorganic solid-matter scintillator that incorporates at least one decay time component greater than 100 ns and measures the photons emitted by the scintillator with a fast single-photon counter. The single-photon counter is composed of a fast photomultiplier with high internal amplification, a stabilized high-voltage supply and a fast amplifier/discriminator with standard pulse output. With this arrangement, the measurement of all types of radiation, like alpha, beta, gamma and X radiation, can be performed, with low manufacturing costs for the detector, a high degree of sensitivity especially with regard to low beta energies, only small sensitivity changes over a large temperature range of &#x2212;20 to +50 degrees C., and good long-term stability.
