    • This invention provides an anode-free, passive and versatile cathodic protection method to robustly achieve anti-corrosion purposes on a wide range of materials (including metals, nonmetals and composites) under various situations for very long time, by utilizing beta emitters such as nickel-63. Normally, radioisotopes, other than the beta emitters adopted in this invention, are considered hazardous when applied within our daily environment. For this reason, long-life (e.g., on the order of 100 years, therefore of small decay constant), low-energy (much less than the MeV level) beta emitters, such as the adopted nickel-63, are always overlooked for such crucial anti-corrosion applications.
    • 本发明提供了一种无阳极,被动和通用的阴极保护方法,通过利用β发射体如镍,在许多情况下,在很长的时间内,广泛的材料(包括金属,非金属和复合材料)上实现抗腐蚀目的 -63。 通常,除了本发明采用的β发射体之外,放射性同位素在我们的日常环境中应用时被认为是有害的。 因此,长寿命(例如,100年左右,因此具有小衰减常数),低能量(远低于MeV等级)的β发射体,如采用的镍63,总是被忽视 这种至关重要的防腐应用。
