An electromagnetic pulse protecting method includes: searching a threat 2 that generates an electromagnetic pulse 2a; and generating plasma 6 in a light-condensed point 4 by condensing a laser beam 5 on a light-condensed point 4 in response to detection of the threat 2. Thus, various protection objects which contain a protection object having an electric opening indispensably can be protected from an attack by the electromagnetic pulse.

A radiation measuring apparatus (20) includes a scatterer detector (10A), an absorber detector (10B) and a processing unit (12). Pixel electrodes (2) of the scatterer detector (10A) and the absorber detector (10B) are arranged such that a distance between centers of two neighbor pixel electrodes (2) is smaller than a mean free path of a recoil electron generated in the Compton scattering of an electromagnetic radiation. The processing unit (12) specifies and incidence direction of the electromagnetic radiation based on a recoiling direction to which the recoil electron recoils. In this way, an electron tracking-type Compton camera is realized which confines the incidence direction of the electromagnetic radiation by using the recoiling direction of the recoil electron in a Compton camera using a semiconductor detector.

A method of irradiating an electromagnetic pulse includes specifying a position of a target having electronic equipment; setting the light-condensing point based on the position of the target; and condensing the laser beam to generate plasma in the light-condensing point such that the electromagnetic pulse generated from the plasma is irradiated to the electronic equipment. In this way, a method and system for irradiating an electromagnetic pulse are realized which can irradiate the electromagnetic pulse of a large output while restraining diffusion of the electromagnetic pulse.
