Radioactive decay
The idea of a Natural nuclear fission reactor is pretty interesting, no? However, I removed your section about background-radiation sources, since the page is about the physics and related issues, not environment or biological effects. We already have a whole separate page about Background radiation. DMacks 17:04, 8 May 2007 (UTC)

License tagging for Image:Rimfire22(2).jpg
Thanks for uploading Image:Rimfire22(2).jpg. Wikipedia gets thousands of images uploaded every day, and in order to verify that the images can be legally used on Wikipedia, the source and copyright status must be indicated. Images need to have an image tag applied to the image description page indicating the copyright status of the image. This uniform and easy-to-understand method of indicating the license status allows potential re-users of the images to know what they are allowed to do with the images.

For more information on using images, see the following pages:
 * Image use policy
 * Image copyright tags

This is an automated notice by OrphanBot. If you need help on selecting a tag to use, or in adding the tag to the image description, feel free to post a message at Media copyright questions. 17:10, 8 May 2007 (UTC)

Orphaned non-free media (File:Holt'sbitter.jpg)
Thanks for uploading File:Holt'sbitter.jpg. The media description page currently specifies that it is non-free and may only be used on Wikipedia under a claim of fair use. However, it is currently orphaned, meaning that it is not used in any articles on Wikipedia. If the media was previously in an article, please go to the article and see why it was removed. You may add it back if you think that that will be useful. However, please note that media for which a replacement could be created are not acceptable for use on Wikipedia (see our policy for non-free media).

If you have uploaded other unlicensed media, please check whether they're used in any articles or not. You can find a list of 'file' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "File" from the dropdown box. Note that all non-free media not used in any articles will be deleted after seven days, as described on criteria for speedy deletion. Thank you. Calliopejen1 (talk) 05:05, 3 October 2011 (UTC)
