| 1. | What levels of ionising radiation are safe
致电离辐射处于哪个水平才属安全？ |
| 2. | Various instruments are used to measure ionising radiation
不少仪器可用以量度致电离辐射。 |
| 3. | What is the added risk of cancer from ionising radiation
因致电离辐射而患上癌症的额外风险有多大？ |
| 4. | What is the difference between ionising and non - ionising radiation
致电离与非致电离辐射有何分别？ |
| 5. | How is ionising radiation measured
如何量度致电离辐射？ |
| 6. | There are several different types of radiation . a useful way of classifying the different types of radiation is into
辐射的种类有许多，大致可分为致电离与非致电离辐射电磁与微粒辐射。 |
| 7. | Non - ionising radiation such as radio waves , radar and visible light does not have sufficient energy to remove electrons from atoms while passing through matter ; ionising radiation does . are there different types of ionising radiation ? yes
非致电离辐射如无线电波雷达及可见的光线在穿过物质时，并无足够的能量使电子脱离原子，但致电离辐射则可以。 |
| 8. | Cosmic radiation is a naturally occurring ionising radiation that arises from outside the earth . it has two components , solar radiation from the sun and galactic radiation from outside the solar system . it primarily consists of particles such as protons , neutrons and a - particles
宇宙辐射是一种源自地球以外自然产生的致电离辐射，由太阳辐射和太阳系以外的银河辐射组成，主要包含质子中子和粒子等微粒。 |
