RTG 223 Radiation protection

1. The abbreviation of International Commission on Radiation Units and Measurements.
5. The unit of exposure.
6. The equivalent dose of RT for which organ should have the dose limit are 500 mSv per year.
8. Material shielding for gamma ray.
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. The abbreviation of tenth value layer.
14. The spontaneous emission of energy from unstable atom.
17. The part of an atom with a negative electrical charge, which moves around the atom's nucleus.
19. The SI unit of absorbed dose.
20. The disease which is inducing of stochastic effect.
22. The non SI unit of absorbed dose.
23. The particle that be absorbed by aluminum.
24. The abbreviation of disintegration per second.
26. The personal dose monitoring.
27. The amount of ionization in air due to gamma and x-ray.
28. 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.

1. The elements with the same atomic number but different mass numbers.
2. The non SI unit of effective dose.
3. The SI unit of radioactivity.
4. The SI unit of equivalent dose.
5. The radioactive element, mam-made or from natural sources, with a specific atomic weight.
7. The effect that occur with dose-dependent severity. These effects generally do not occur below a certain threshold value.
11. The inverse square law is a technique of external radiation protection.
12. The energy that comes from a source and travels through space and may be able to penetrate various materials
13. The particle is a helium NUCLEUS.
15. The energy deposited in a small volume of matter
16. We called positive electron, positively charged.
18. The disease is abnormal redness and inflammation of the skin caused by deterministic effect.
21. Neutron shielding material.
25. We can call gamma ray and x-ray ray in the other name.
