The compact Raman Lidar is developed for the atmosphere measurement under nuclear environment, in which radiation ionize the water vapor and generate the water-cluster. In this study, the Raman lidar throws the NUV-beam of 349 nm and detects the backscattering echoes of water-Raman (396 nm) and the water-vapor-Raman (400 nm). Am-241 of 9 MBq was used for the radiation source. The results showed that the water-Raman increased and the water-vapor-Raman decreased under the nuclear environment. Its ratio becomes 3 times. It is well coincide with the estimation. The radius of water cluster was estimated 200 nm by the experiment.
