Welcome! Please follow our rules:

1. Ionizing radiation discussion only

This subreddit is for discussion of ionizing radiation such as alpha, beta, gamma, and x-ray. Please do not post about RF, 5G, wi-fi, or common electronic items causing cancer or health issues.

2. Don't be a jerk

Please treat each other respectfully.

3. Do not ask for medical advice

Reddit is not a place for medical advice. Please talk to your doctor or healthcare team about your medical decisions.

4. No promotional activity

Please don't use our community for advertising or promotion. Unsolicited linking of products, services, social media (including youtube channels) etc. is discouraged. In response to questions about products, it's fine to make recommendations - please include an explanation of your input and not simply a link or product name.

5. No fake content posted in bad faith

Any content that has been faked is subject to removal and the user subject to ban at the discretion of the mods. This includes, but is not limited to, photoshops, video editing (including special effects e.g. speckles/compression artefacts), claiming a source is something it is not (e.g. saying a 0.9 Am-241 source is 20 mCi of Co-60), claiming an object is radioactive when it is not, showing false readings that are faked with a hotter source, EMI, photo/video manipulation, or other method, etc.
