Abstract

A device for detection of high-power pulsed microwave radiation, which can be used to ascertain whether an object has been exposed to microwaves having high pulse power which can cause damage to the object. The device includes a vessel (1), for instance in the form of a glass tube, which encloses an ionizable gas. When the vessel is exposed to a microwave pulse, the gas is ionized by the electric field from the microwave pulse. If the field intensity is high enough to cause the gas to reach the level of ionization at which a discharge is generated, a pulse of light appears in the vessel (1). This pulse of light is recorded with a means (2) having "memory function", for instance a film, which is arranged in connection with the vessel (1) and gives a remaining recording and thereby indicates that the vessel (1) has been exposed to a microwave pulse having a pulse power exceeding a certain level.
