3. The unit of exposure.
6. occur below a certain threshold value.
7. The SI unit of equivalent dose.
9. The personal dose monitoring.
12. The SI unit of radioactivity.
14. The radioactive element, mam-made or from natural sources, with a specific atomic weight.
17. Material shielding for gamma ray.
18. The non SI unit of absorbed dose.
20. The spontaneous emission of energy from unstable atom.
22. The abbreviation of tenth value layer.
24. The dose representation the total body could receive and could be assessed the potential for long-term effects that might occur in the future.
26. The disease is abnormal redness and inflammation of the skin caused by deterministic effect.
27. Neutron shielding material.

2. The elements with the same atomic number but different mass numbers.
4. The amount of ionization in air due to gamma and x-ray.
5. The abbreviation of disintegration per second.
8. The particle is a helium NUCLEUS.
10. The energy deposited in a small volume of matter
11. The abbreviation of International Commission on Radiation Units and Measurements.
13. The energy that comes from a source and travels through space and may be able to penetrate various materials
15. The effect that occur with dose-dependent severity. These effects generally do
16. We can call gamma ray and x-ray ray in the other name.
19. The inverse square law is a technique of external radiation protection.
21. 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.
23. We called positive electron, positively charged.
24. The part of an atom with a negative electrical charge, which moves around the atom's nucleus.
