This tutorial provides 2 CEUs and is ideal for:

 Radiation Physicists. All 53.0 CEUs have been approved by CAMPEP for Medical Physics Continuing Education Credits.
 Nuclear Medicine and Radiology Technologists. The VOICE program of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) has reviewed this program and approved it for a maximum of 53 continuing education hours. Because these tutorials have been approved by the VOICE Program, they are accepted for CE credit in all 50 states and by ARRT and NMTCB, even if you are not a VOICE/SNMMI member.
 Physicians requiring CME Credits to maintain IAC Accreditation. All 53.0 CME Credits have been approved by the IAC and are listed on the resources page of their website.

Purchase Tutorial: Payment link (Credit Cards/Paypal)RADIOACTIVE DECAY: 2 CEU This tutorial gives an overview on Interaction of Ionizing Radiation With Matter
Objectives for Tutorial on Concepts and Mathematics of Radioactive Decay
Topics to be Covered:
 Definition of radioactive decay, the exponential law that it follows, and a definition of halflife.
 Graphic representation of radioactive decay as a function of time, both prospectively and retrospectively
 The classic mathematical formula for radioactive decay and a more modern formula with its increased simplicity.
 Mathematical problem solving
 Biexponential decay and graphical analysis
After completion of this tutorial, one should be able to:
 Define radioactive decay and halflife.
 Explain what happens to activity of a source going prospectively and retrospectively in time, that is, halflives from now and halflives in the past
 Using graphical analysis, determine halflife from a semilogarithmic plot of activity vs time.
 State mathematical relationship between l (the decay constant) and the halflife and compare to the mathematical relationship between m (the linear absorption coefficient) and the halfvalue layer.
 Write the equations for calculations involving activity decrease as a function of the number of halflives
 Work a variety of math problems involving change of beam intensity with change of number of HVLs or TVLs.
RECEIVING YOUR CE CREDIT:
If you have taken one of the tutorials, received a score of 80% or above, and wish to receive CE credit: Make sure you submit all of the requested information when taking the test. It’s not necessary to send us the score sheets since we receive them electronically when you submit your answers for scoring.Within 24 hours of receipt of your submitted score sheets and payment for the tutorial(s), we will do all of the following:1. Send a certificate to you via email
2. Send a certificate to you via US Mail
3. All members of the SNMMI will have to selfreport their CE Credits on the SNMMI Website (www.snmmi.org). We will automatically send detailed selfreporting instructions to you along with your CE Credit Certificate.
If you have any problems with the selfreporting system, please contact the VOICE Coordinator directly at 703 7089000. ).If paying by check, please make payable to Consultants in Nuclear Medicine and mail your payment to: Consultants in Nuclear Medicine 2910 W.
