PURPOSE:To allow a skilled worker to undertake a work and shorten a working time by reducing an exposure amount for a work at a place where the dose rate of a radiation is high. CONSTITUTION:At a pre-work meeting, an instruction is given for a worker to stay away as far as possible from a pipe line 2, a valve 1, a recirculation pump 4 or the like as large equipment, and a piping section is irradiated in orange color or the like over an area 12, using a laser beam emitter 11. As a result, it can be understood that a work should be undertaken at a place away from the pile line 2 or the pump 4. Furthermore, a worker overhauls and checks a valve 3 from the opposite side of the valve 1. In this case, a laser beam has high directivity, and can indicate only the required irradiation section of plant equipment as an object in an efficient and concentrated way, in line with the shape of the equipment.
