E-CodeGamma shielding with Taylor buildup — a TI-84 Plus CE program
TAYLORB is a TI-BASIC program for the TI-84 Plus CE. Point isotropic gamma source behind a slab: Taylor buildup factor, unshielded, uncollided and total flux at the detector, and (optionally) the shield thickness that brings the flux down to a target.
What it asks for and what it shows
It asks for 6 values at its prompts. In the example below it shows B, PHI0, PHIU, PHI, MU X, X CM.
Example run
One of its oracle test cases: “1 Ci source behind 50 cm of water-like shield”. The inputs are typed in order, and the results are the values the case expects on the screen.
| Step | Value |
|---|---|
| You enter | |
| Input 1 | 37000000000 |
| Input 2 | 0.0707 |
| Input 3 | 50 |
| Input 4 | 100 |
| Input 5 | {11,⁻0.104,0.03} |
| Input 6 | 1 |
| The screen shows | |
B= | 6.893745104 |
PHI0= | 294436.6447 |
PHIU= | 8585.406572 |
PHI= | 59185.60453 |
MU X= | 3.535 |
X CM= | 235.0137731 |
How it's checked
6 test cases, each checked against an independent method. Replayed key by key on a virtual TI-84 Plus CE, they make 41 checks.
How E-Code checks every program
Run it or put it on your calculator
- Open the library in the TI-84 Plus CE calculator and pick “Gamma shielding with Taylor buildup” (TAYLORB).
- Put it on your own calculator with a computer and a USB cable, or type it in by hand.
