3D Cone Beam Computerized Tomogram (CBCT)

3D  CBCT produced better image quality with a very much lower radiation dose  per examination) (Hashimoto et al. 2003)

Type of Exposure Dose Received
Dental X-ray
3 D Cone Beam CT
0.01 mSv
1.19mSv
Chest X-ray 0.02 mSv
Cosmic radiation (from sky) at sea level 0.24 mSv/year
Terrestrial radiation 0.25 mSv/year
Natural radiation in the human body

 

0.40 mSv/year
Average individual background radiation dose (Vancouver, Canada)

 

1.19 mSv/year
Average individual background radiation dose (United States) 3.0 mSv/year
Smoking 1.5 packs/day 13- 60 mSv/year
  15 mSv/scan
Current average maximum limit for nuclear workers

 

20 mSv/year
Medical CT scan (newborn) 30 mSv/scan
Background radiation in parts of Iran, India & Europe 50 mSv/year
Lowest carcinogenic level (lowest level at which any increase in cancer risk is clearly evident) 100 mSv/year
Elevated limit for workers during Fukushima emergency 250 mSv/year
Criterion for relocating people after the Chernobyl accident 350 mSv/year
At one point, radiation levels near the Fukushima nuclear plant 400 mSv/year
The cumulative amount would probably cause a fatal cancer many years later in five out of every 100 persons 1,000 mSv (1 sievert)/year

 

Radiation Dose Health Risks/ Radiation Sickness
0 – 250 mSv Minimal/No Risk
250 – 1000 mSv Some people feel nausea and loss of appetite; Bone marrow, lymph nodes, spleen damaged.
1000 – 3000 mSv Mild to severe nausea, loss of appetite, infection; More severe bone marrow, lymph node, spleen damage; Recovery probable, not assured.
3000 – 6000 mSv Severe nausea, loss of appetite; Hemorrhaging, infection, diarrhea, peeling of skin, sterility; Death if untreated.
6000 – 10,000 mSv Above symptoms plus central nervous system impairment; Death expected.
10,000 mSv Incapacitation and death.
