NRRPT Prep Complete Study Guide Exam
Exam Coverage
Exam coverage for the NRRPT Prep Complete Study Guide Exam
includes comprehensive radiologic and radiation therapy principles
required for certification through the National Registry of Radiation
Protection Technologists (NRRPT). It focuses on radiation physics,
radiation protection, dosimetry, imaging principles, equipment
operation, and quality assurance. The exam also evaluates
understanding of radiation safety standards, biological effects of
radiation, patient positioning, exposure techniques, and regulatory
compliance.
Emphasis is placed on applying radiation safety practices, minimizing
exposure to patients and staff, understanding technical imaging
,processes, and demonstrating competency in radiologic procedures
and protection standards. ☢️📘
,Question Number: 1
Fundamentals of Radiation Protection
A sample of I-131 (half life = 8 days) is kept for 80 days, at which time
the activity is 1 µCi . What was the original activity?
A) 2.0 mCi
B) 1.0 mCi
C) 1.5 mCi
D) 3.5 mCi
E) 4.0 mCi
The correct answer is: B
After 10 half lives, the remaining activity is approximately 1000th of the
, original amount. Therefore, if there was 1µCi left after 10 half lives, then
there must have been 1000 times more to start with. Hence, 1 µCi *
1000 = 1 mCi.
