Accute irradiation is covered by this definition and the victim will also benefit from presumptive evidence. However compensation for stochastic sub-acute injuries from ionizing radiation, in the framework of insurance law, may be open to dispute given the definition of an industrial accident, the short prescription period and the burden of proof required for compensation of delayed injuries (NEA)
