| Portion used |
Full image. |
| Low resolution? |
The image is of a low size and resolution, sufficient to maintain the quality intended by the company, without being unnecessarily high resolution. At a lower size the compound would look just like an ordinary powder. It does not limit the copyright owner's rights to market or sell the work in any way. |
| Purpose of use |
The image is used to illustrate and identify the radioactive compound in its pure form. |
| Replaceable? |
A free replacement image could not be created due to national security and safety restrictions against public handling or viewing the compound. This image is one of the very few, or quite possibly the only one published on the pure compound. |
