NEUTRARIZATION APPARATUS EMPLOYING α RAY

摘要

[PROBLEMS] Neutralization equipment employing α-rays in which atmospheric ions produced through ionization by irradiating α-rays can touch an object to be neutralized efficiently while surely avoiding such a situation as the object to be neutralized is irradiated directly with α-rays emitted from an α-ray source. [MEANS FOR SOLVING PROBLEMS] The neutralization equipment employing α-rays comprises an α-ray shield box (10) provided with an ion discharging opening (11), and one or more α-ray sources (12) being contained in the α-ray shield box, wherein atmospheric ions produced through ionization by irradiating α-rays emitted from respective α-ray sources (12) are discharged from the ion discharging opening (11) to touch an object to be neutralized. The α-ray sources (12) in the α-ray shield box (10) are positioned such that the α-ray particles being emitted therefrom do not reach the object to be neutralized and atmospheric ions are produced through ionization at a position facing the ion discharging opening (11).
