[Criterial parameter of hygienic regulation for exposure to rarely repeated ultrashort electromagnetic impulses].

The authors justified an estimated induced current density as a criterial parameter for hygienic regulation of exposure to rarely repeated ultrashort electromagnetic impulses of nanosecond duration in electrical discharge devices applied in scientific research. The authors defined a threshold for harmful effects of the impulse, set maximal allowable levels of exposure for the devices operators. Methodic and regulatory documents were specified and approved to provide electromagnetic safety for personnel working in impulse fields.
