Accepted Answer

DOT 49 CFR Parts 171-173

Answer

Question 3

During a radiographic operation, a radiographer's alarming ratemeter goes off unexpectedly, and the survey meter confirms that the source is not secured in its shielded position. What is the radiographer's most critical immediate responsibility?

Accepted Answer

Secure the restricted area boundary and prevent unauthorized entry.

Answer

In an emergency where a source is unshielded, the first and most critical responsibility is to protect people from exposure. This involves securing the restricted area to prevent anyone from entering and being exposed to the unshielded source. Notifying the RSO is also crucial, but securing the area comes first.

Question 4

Which of the following records must a licensee maintain regarding industrial radiographic operations?

Accepted Answer

Quarterly inventory of sealed sources

Answer

According to 10 CFR Part 34, licensees are required to conduct a physical inventory of all sealed sources every three months (quarterly) to ensure they are accounted for.

Question 5

Under 10 CFR Part 34, when performing radiography at a temporary job site, a qualified radiographer must be accompanied by at least one other individual. What is the minimum qualification for this second individual?

Accepted Answer

An individual who has met the requirements of a radiographer's assistant.

Answer

10 CFR 34.41(a) requires that when radiography is performed at a location other than a permanent installation, the radiographer must be accompanied by at least one other qualified radiographer or a radiographer's assistant. This ensures a second person is present who can observe, provide immediate assistance, and prevent unauthorized entry.
