The monitoring techniques for airborne radioiodine, based on the findings at JAERI and the works elsewhere are described:
1) Properties of the airborne radioiodine encountered in radiation work.
2) Performance of the iodine sampler consisting of a cellulose asbestos filter paper and a charcoal-loaded filter paper or charcoal cartridges, or the three.
3) Improvement of the sampler by use of charcoal impregnated with chemicals such as triethylenediamine (TEDA) or by dehumidification through heating the sampling air.
4) Practices of the monitoring in radiation protection.
Problems in environmental monitoring of the airborne radioiodine from a light water power reactors and fuel reprocessing plants are also presented.
