Across
  1. 3. The unit of exposure.
  2. 6. The personal dose monitoring.
  3. 8. Neutron shielding material.
  4. 10. The spontaneous emission of energy from unstable atom.
  5. 11. The abbreviation of tenth value layer.
  6. 13. The equivalent dose of RT for which organ should have the dose limit are 20 mSv per year.
  7. 14. Material shielding for gamma ray.
  8. 16. The dose representation the total body could receive and could be assessed the potential for long-term effects that might occur in the future.
  9. 22. The amount of ionisation in air due to gamma and x-ray.
  10. 24. The SI unit of equivalent dose.
  11. 25. The energy that comes from a source and travels through space and may be able to penetrate various materials
  12. 28. The disease which is inducing of stochastic effect.
  13. 30. The SI unit of absorbed dose.
Down
  1. 1. The particle that be absorbed by aluminum.
  2. 2. We called positive electron, positively charged.
  3. 4. The inverse square law is a technique of external radiation protection.
  4. 5. A radionuclide is a radioactive element, mam-made or from natural sources, with a specific atomic weight.
  5. 7. The effect that occur with dose-dependent severity. These effects generally do not occur below a certain threshold value.
  6. 9. The disease is abnormal redness and inflammation of the skin caused by deterministic effect.
  7. 12. The energy deposited in a small volume of matter
  8. 15. The SI unit of radioactivity.
  9. 17. The abbreviation of disintegration per second.
  10. 18. 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.
  11. 19. The part of an atom with a negative electrical charge, which moves around the atom's nucleus.
  12. 20. The non SI unit of effective dose .
  13. 21. The elements with the same atomic number but different mass numbers.
  14. 23. We can call gamma ray and x-ray ray in the other name.
  15. 26. The particle is a helium NUCLEUS.
  16. 27. The abbreviation of International Commission on Radiation Units and Measurements.
  17. 29. The non SI unit of absorbed dose.
