早期放射性现象研究中,人们曾观察到某些无机盐类溶液在放射线照射下,会出现一种微弱的蓝白色闪光,当时人们认为这是一种荧光现象。1934年切伦柯夫等在实验和研究中也发现一些液体在γ射线的作用下也会产生发光现象,但光强度较弱,呈淡蓝紫色且具有连续光谱的性质。经进一步研究表明它不是荧光而是一种新的辐射。后称之为切伦柯夫辐射(Cerenov Radiation)。随之对此辐射现象提出了理论上的解释。指出 In early studies of radioactivity, it was observed that some inorganic salt solutions show a faint blue-white flash upon exposure to radiation, a phenomenon considered fluorescent at that time. In 1934 Cerenkov et al. Also found in some experiments and studies that some liquids also emit light under the action of gamma rays, but the light intensity is weak, light blue-purple and has continuous spectral properties. After further research shows that it is not a fluorescence but a new radiation. Later called Cerenov Radiation. Followed by the radiation phenomenon proposed a theoretical explanation. Pointed out
