7. The SI unit of absorbed dose.
8. The spontaneous emission of energy from unstable atom.
10. The energy that comes from a source and travels through space and may be able to penetrate various materials
13. The SI unit of equivalent dose.

25. The non SI unit of absorbed dose.
26. The SI unit of radioactivity.
29. The particle that be absorbed by aluminum.
30. We called positive electron, positively charged.

2. The effects that occur by chance and which may occur without a threshold level of dose, whose probability is proportional to the dose and whose severity is independent of the dose.
4. The effect that occur with dose-dependent severity. These effects generally do
8. The unit of exposure.
9. The inverse square law is a technique of external radiation protection.
11. The radioactive element, mam-made or from natural sources, with a specific atomic weight.
