Abstract: The invention relates to a blocking device (5) for stopping solid bodies that have been irradiated or that are to be irradiated in a conduit system (2) which is used to transport the solid bodies by means of a propelling fluid into and out from a nuclear reactor (1). The blocking device has at least one main body (52) with a continuous channel (521) for the solid bodies and an actuator (58), which is arranged inside the main body (52) and which is adjustable relative to the main body (52) between an open position and a closed position in such a way that the channel (521) for the solid bodies is open in the open position and is closed in the closed position. The actuator (58) can be brought from the open position into the closed position and from the closed position into the open position by being displaced relative to the at least one main body (52). The blocking device can be used in particular as part of an aeroball measurement system (3) or as part of a nuclide activation system (4).

Abstract: A composition that includes ethylhexyl sulfate or a salt thereof, an alkylbenzenesulfonic acid or a salt thereof, and a carrier. The composition can be used for killing or inhibiting a microorganism or pathogen (e.g., bacteria, gram-negative bacteria, gram-positive bacteria, enteric bacteria, virus, fungus, mold, mildew or powdery mildew), located on a topical surface of an animal, located on a surface of an object that will contact a topical surface of an animal, or a combination thereof, wherein the microorganism or pathogen is associated with the transmission of communicable diseases.

Abstract: A composition that includes ethylhexyl sulfate or a salt thereof, an alkylbenzenesulfonic acid or a salt thereof, and a carrier. The ethylhexyl sulfate, or salt thereof, and the alkylbenzenesulfonic acid, or salt thereof, are present in a weight ratio of at least about 1:2. The composition can be used for killing or inhibiting a microorganism or pathogen (e.g., bacteria, gram-negative bacteria, gram-positive bacteria, enteric bacteria, virus, fungus, mold, mildew or powdery mildew).
