When evaluating grids, a radiograph should be produced at approximately which density on the film?

Explanation:
Density on a radiograph reflects optical density—the darker the image, the higher the density. For grid evaluation, you want a middle-ground exposure so the grid lines are clearly visible without the image being saturated. An optical density around 1.2 provides that balance: it’s dark enough to reveal the grid pattern and any irregularities, yet not so dark that contrast is lost and subtle features become hard to judge. If the density is higher, the image can become too dark, masking grid issues; if it's lower, the grid lines may be faint and difficult to assess. So, target about 1.2 for reliable grid QA imaging.
