Calculators
Last verified on October 10, 2017
You have two calculator choices for the Part 1 Exam—both General and Clinical—and the Part 2 Exam. No calculator is needed for the Part 3 Exam (Oral).
You may bring a TI-30XS calculator with you. The calculator must be that specific model. Texas Instruments makes a variety of calculators, but only the TI-30XS will be accepted.
If your calculator is not accepted or you choose not to bring a calculator, an emulated version of the TI-30XS calculator will be available in the Pearson VUE exam interface. To familiarize yourself with its operation and the Pearson VUE exam interface, please visit
http://www.pearsonvue.com/ABR and click the link for the “Pearson VUE testing tutorial and practice exam." Please note that the calculator provided during the exam is a software program designed to emulate the handheld TI-30XS, not the actual handheld device itself.
As has always been the case,
absolutely no other personal electronic, computing, or calculator devices are permitted in the exam areas. Although the calculator provided will be a software program, it may be helpful to obtain the actual device prior to the test and practice with it, as the calculator used in the exam will look and function very similarly to the handheld model.
Exercises for use with the TI-30XS calculator
The following exercises are not indicative of actual questions on the ABR exam. They are intended to help you practice with the calculator. You are encouraged to try other examples of calculations that would arise as a routine part of your daily work.
Calculate the decay constant of
^{ 99m}Tc from its half-life of 6.02 hr.
What is the value of the first spherical Bessel function (sin(x)/x) at 0.25 radians? This is also sometimes called the sinc function.
- Use of Hyperbolic functions:
The Gateway Arch in St. Louis is famous as an inverted catenary that is given by y=693.9 - 68.8 cosh (0.01x). When x=100 ft., what is the value of y?
The sensitivity of a photomultiplier tube is often approximated as a cos
^{3} θ function. If the relative sensitivity of the tube is 0.90, what is the effective angle θ in radians?
An 86-MBq source of
^{ 99m}Tc is allowed to decay for 14.6 hrs. At the end of that period, what will its activity be?
- Exponential function and use of memory:
A
^{ 99}Mo/
^{ 99m}Tc generator is eluted at time zero. This reduces the activity of
^{ 99m}Tc in the generator to zero. If the activity of
^{ 99}Mo in the generator at time zero is 861 MBq, what will the activity of
^{ 99m}Tc be at 4 hrs? (The half-life of
^{ 99}Mo is 67 hrs. Use the Bateman equations.)
