The Influence of ~(14)C-urea Breath Test on Environment

  • ~(14)C-urea breath test(~(14)C-UBT) is introduced briefly, which shows that ~(14)C-UBT is a excellent noninvasive method for detecting helicobacter pylori(HP) with safety, simplicity, and speed. The amount of ~(14)C released to environment by practising ~(14)C-UBT is much less than that of (~(14)C) in environment from both natural and artificial sources. The ~(14)C released by ~(14)C-UBT with 27.75 kBq each time and 10~7 times per year is only 0.028% of ~(14)C generated from natural sources per year, if this quantity of ~(14)C-UBT is used per year for ever, it brings an individual person to bear an extra effective radiation dosage of 3.33×10~(-3) μSv. So the influence of ~(14)C-UBT on environment could be neglectible.
