RTG 223 Radiation protection

2. The SI unit of absorbed dose.
4. The SI unit of equivalent dose.
7. The SI unit of radioactivity.
9. The abbreviation of tenth value layer.
11. The energy deposited in a small volume of matter
12. We can call gamma ray and x-ray ray in the other name.
15. The effect that occur with dose-dependent severity. These effects generally do not occur below a certain threshold value.
18. The personal dose monitoring.
20. The amount of ionization in air due to gamma and x-ray.
22. The non SI unit of absorbed dose.
23. The particle is a helium NUCLEUS.
24. The abbreviation of disintegration per second.
25. The radioactive element, mam-made or from natural sources, with a specific atomic weight.
27. The disease which is inducing of stochastic effect.
29. The inverse square law is a technique of external radiation protection.

1. Neutron shielding material.
3. The disease is abnormal redness and inflammation of the skin caused by deterministic effect.
5. The unit of exposure.
6. The part of an atom with a negative electrical charge, which moves around the atom's nucleus.
8. The dose representation the total body could receive and could be assessed the potential for long-term effects that might occur in the future.
10. The elements with the same atomic number but different mass numbers.
13. The particle that be absorbed by aluminum.
14. The effect 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.
16. The spontaneous emission of energy from unstable atom.
17. We called positive electron, positively charged.
19. Material shielding for gamma ray.
21. The equivalent dose of RT for which organ should have the dose limit are 500 mSv per year.
22. The energy that comes from a source and travels through space and may be able to penetrate various materials
26. The abbreviation of International Commission on Radiation Units and Measurements.
28. The non SI unit of effective dose.
