A study ascertained that 87-206 microsievert ([micro]Sv) radiation is taken up by CBCT; 14.2-24.3 [micro]Sv by panoramic radiography; 10.4 [micro]Sv by lateral cephalometry; and 13-100 [micro]Sv with full mouth periapical radiography (9).

The dosage of radiation at that site stands at 0.3 microsievert per hour, the officials said.
Consider just this one fact: Through a Freedom of Information Act request it was discovered that on March 17, 2011, the NRC projected that California infants would receive "very high doses," about a 40,000 microsievert dose, of radiation to the thyroid from Fukushima fallout over the course of a year.
All individuals within 200 km of the site should be evacuated if the local air dose is greater than one microsievert per hour.
Yet keeping track of which was more (millisievert: Sv 1/1,000, and microsievert: Sv 1/1,000,000) was a challenge.
The natural radiation level is 0.1 microSievert per hour and controls on ships coming from Japan will be carried out with a threshold of an additional 0,2 microSievert per hour on top of natural radiation levels, said the commissioner.
(One millisievert = 1,000 microsieverts; 1 microsievert = 0.1
Radiation levels at the evacuation centre were within a normal range of about 0.16 microsievert, according to a Reuters geiger counter reading.
4 reactors ''would certainly have negative effects on the human body.''The utility firm said later in the day the massive radiation amount of 400 millisievert per hour, or 400,000 microsievert, was recorded around debris in front of the No.
