Dose in x-ray diagnostics
The radiation dose that a person receives during the passage of diagnostic x-ray depends on the type of this diagnostic, that is, which organ must be subjected to research. So, one fluorogram provides a person receiving a radiation dose amounting from 0.6 to 0.8 mSv (mSv), with the mammary glands, which is called a mammogram, are 0.2 - 0.3 mSv, the bones of the hip joint by 0.3 - 0.5 mSv.
Fairly common in dental practice x-rays of the tooth gives a dose of radiation equal to 0,15-0,35 mSv. However, often there are situations when a person simultaneously treats several teeth that patients receive the highest radiation dose. Although this parameter is not directly proportional to the number of diagnosed teeth, it still increases depending on the number of shots. For example, simultaneous x-ray diagnosis 10 teeth provides patient radiation dose equal to 1.1 to 1.8 mSv.
Safe dose
However, all of these doses of radiation, according to doctors, are completely safe for humans. So, one of the most dangerous effects of x-ray irradiation is the occurrence of cancer. However, experts in Oncology noted that the marked increase in the frequency of their appearance occurs only if the radiation dose received by the person, exceeds 150 mSv in a year.
From these figures it becomes clear that risk, a category that is able to get such a dose of x-rays, includes people who are seriously ill or have suffered extremely life-threatening injury that doctors had to regularly conduct x-ray examination. And using the standard annual pass fluoroscopy, mammography and other periodic diagnostic measures to limit the dose is almost impossible.
However, for those who are still afraid of the negative influence of x-irradiation on your body, you should remember that minimizing the impacts can be asked in a diagnostic study special protective apron, which should cover parts of the body not involved in the diagnostics: such devices should be available in each such account. In addition, if you are observed in the same medical facility, your card should present information about the radiation doses received during the year.
