1. **State the problem:** We are given uranium readings at two points in the y-direction: 468ppm and 252ppm. We need to find the uranium reading at a point between these two readings assuming equal spacing. 2. **Understand the concept:** Since the traverse is equally spaced, the uranium reading between the two points can be found by averaging the two given values. 3. **Calculate the average:** $$\text{Average uranium reading} = \frac{468 + 252}{2}$$ 4. **Perform the calculation:** $$= \frac{720}{2} = 360$$ 5. **Conclusion:** The uranium reading between the two given points in the y-direction is **360ppm**.
