电视机、电脑视屏与β辐射的关系

Relation between Television and Computer Screen and β Radiation

对电视机、电脑视屏显象管玻壳成分进行β放射性活度测定及β剂量的计算。结果证明,视屏的固有电离辐射——β射线来自玻璃原材料,所产生的β剂量取决于原材料成分中天然放射性核素的种类、含量及所用的份额。由此产生的β剂量对公众的健康不会产生有害影响。

The β-ray activity and β -ray dose from TV and computer screen have been measured. It was affirmed that intrinsic radiation of screen β-ray came from raw materials and glass. The amount of βdose obtained depends on the sorts, contents and portion of natural radioactive elements used in the raw meterials. The β -ray dose from them has no harmful effect on human health.
