RTG 223 Radiation protection

1. The elements with the same atomic number but different mass numbers.
4. We can call gamma ray and x-ray ray in the other name.
5. The amount of ionization in air due to gamma and x-ray.
8. Neutron shielding material.
13. The energy deposited in a small volume of matter
15. The effect that occur with dose-dependent severity. These effects generally do not occur below a certain threshold value.
18. The particle that be absorbed by aluminum.
20. The abbreviation of disintegration per second.
21. The SI unit of radioactivity.
22. The inverse square law is a technique of external radiation protection.
25. The SI unit of equivalent dose.
26. The SI unit of absorbed dose.
28. The disease which is inducing of stochastic effect.
29. The part of an atom with a negative electrical charge, which moves around the atom's nucleus.

2. The disease is abnormal redness and inflammation of the skin caused by deterministic effect.
3. The equivalent dose of RT for which organ should have the dose limit are 500 mSv per year.
6. 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.
7. The radioactive element, mam-made or from natural sources, with a specific atomic weight.
9. 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. We called positive electron, positively charged.
11. The non SI unit of absorbed dose.
12. The energy that comes from a source and travels through space and may be able to penetrate various materials
14. The spontaneous emission of energy from unstable atom.
16. Material shielding for gamma ray.
17. The unit of exposure.
19. The particle is a helium NUCLEUS.
23. The abbreviation of International Commission on Radiation Units and Measurements.
24. The abbreviation of tenth value layer.
27. The non SI unit of effective dose .
30. The personal dose monitoring.
