Optimizing Radiation Exposure Tests
Is the radiation exposure test optimized for linearity?
Exposures made at 100 mA, 200 mA, and 300 mA produced mR readings of 40 mR, 76 mR, and 126 mR, respectively. Does this pass the mA linearity test?
- Yes
- No
Answer:
No, the exposures do not pass the mA linearity test because the mR readings are not directly proportional to the mA values.
To determine if the exposures pass the mA linearity test, we need to check if the mR readings are directly proportional to the mA values. If the relationship is linear, the mR readings should increase in proportion to the mA values.
To test this, we can calculate the mR/mA ratios for each set of readings:
- For 100 mA: 40 mR / 100 mA = 0.4 mR/mA
- For 200 mA: 76 mR / 200 mA ≈ 0.38 mR/mA
- For 300 mA: 126 mR / 300 mA = 0.42 mR/mA
Since the ratios are not equal, the readings do not follow a linear relationship. Therefore, the answer is No, the exposures do not pass the mA linearity test.
