Abstract: A method as well as a composite material for detecting free neutrons are disclosed that include a converter material, which is configured to generate in response to a capture of neutrons a secondary radiation, and a detector material, which is configured to store an information relating to the secondary radiation and to release it again in a later evaluation by optically stimulated luminance. The converter material and the detector material each are present in a plurality of particles, which are jointly present in the composite material as material mixture. In order to improve the detection of neutrons with regard to a person dosimetry, that is the estimation of a dose absorbed by a human, it is envisaged that the detector material is formed from beryllium oxide and/or the converter material is formed from lithium tetraborate.

Abstract: Described is a sterilization chamber for sterilizing objects for application in a process in which a vapour composite, composed of water vapour and hydrogen peroxide vapour, is guided without a carrier gas flow into the sterilization chamber in which a vacuum prevails, whereby the vapour composite settles on the surfaces of the objects to be sterilized and on the surfaces of the sterilization chamber in the form of a condensation layer, which is suctioned off by means of further evacuation of the sterilization chamber after a certain reaction time. In accordance with the present invention, the surfaces of the sterilization chamber consist of poor heat-conducting, water-repellent material.

Abstract: Described is a process for sterilizing objects in a sterilization chamber in which a vacuum prevails, in which sterilization chamber a vapour mix consisting of water steam and hydrogen peroxide steam is fed without the use of carrier gas. The vapour mix is deposited in the form of a condensate layer abruptly on the surfaces of the objects to be sterilized and on the surfaces of the sterilization chamber. The condenste layer is subsequently sucked out by means of further evacuation of the sterilization chamber. In accordance with the present invention, the surfaces of the objects to be sterilized and/or the surfaces of the sterilization chamber are pre-heated to a pre-determined temperature.
