A new protective method to reduce radiation exposure

Hisashi Koga

Abstract

Radiation protection depends on three fundamental factors: exposure time, distance, and shielding. Ishii et al. described a new method for radiation shielding, called Separation between Two Spaces (STS) (1). The basic principle of STS method is a separation of the space around operative table into two spaces using a lead protector: one space contains the patient, operation table, X-ray tube and image intensifier, and the other space is the rest of the operation room. The operators and operative staffs are doing own job in the latter space.
