Radiation Protection of Pregnant Women

Is there a safe level of radiation exposure for a patient during pregnancy?

Dose boundaries do not apply for radiation exposure of patients, since the decision to use radiation is reasonable depending upon the individual patient situation. When it has been decided that a medical procedure is justified, the procedure should be optimized. This means that the conditions should achieve the clinical purpose with the appropriate dose. Dose limits are determined only for the staff and not for patients.

Exopsure Time for Dental Radiography

The exposer time for dental radiography is dependent upon the speed of the film whether its ‘D’ or ‘E’. The exposer time for various areas is given in the table below.

For exact data, you can see the instructions written on the inner side of the carton of the film. The modern microprocessor controlled radiography machines are coming with software that takes care of everything. You need to place the film properly, choose whether the patient is an adult or child, choose the tooth/area desired and shoot the film. You must take care of yourself and your staff for radiation protection. For radiation protection, read the article given below:
