Study on a New Label Dosimeter for Radiation Processing

Journal of Isotopes, 2016
In order to monitor the absorbed dose of goods in 60Co γ-rays and electron beams, a new label dosimeter had been developed for dose measurements. The label dosimeter had a multilayer structure, and the core of which was a layer of radiochromic film.

Quasi-continuous time-stretched photon Doppler velocimetry

Frontiers in Physics, 2022
In transient high-speed scenes such as chemical explosions, magnetic compression, electric explosion, and laser-driven flyer, the target object can accelerate from 0 to tens of km/s in a few nanoseconds. The time-stretched photon Doppler velocimetry uses
