Buying advice

When choosing a Geiger counter, consider the types of radiation you need to detect (alpha, beta, gamma, X-ray), sensitivity (measured in CPM or µSv/h), and features like data logging, Bluetooth connectivity, and alarm thresholds. For most household or hobbyist use, a mid-range model with a good balance of accuracy and price is sufficient. Ensure the product is from a reputable brand and check for calibration certificates. Also, note that Amazon's category may include some low-quality items; stick with well-reviewed products from established manufacturers.
