- 13:4113:41, 30 March 2025 diff hist +88 Fear of radiation/Debate Guide →Guide to Acronyms and Abbreviations: The example above (6.3 mGy per hour from ingested Po-210) is a dose of 63 mSv per hour.
- 13:3413:34, 30 March 2025 diff hist +284 Fear of radiation/Debate Guide →Guide to Acronyms and Abbreviations: One microgram of Po-210 emits 140 microwatts of radiant energy, in the form of alpha particles. If distributed over an entire body (80 kg of tissue) absorption would be 6.3 mGy per hour.
- 12:2812:28, 30 March 2025 diff hist −69 m Fear of radiation/Debate Guide →Guide to Acronyms and Abbreviations: simplify to "One Bq is one nuclear decay per second."

- 11:1111:11, 30 March 2025 diff hist +234 Fear of radiation/Debate Guide →Guide to Acronyms and Abbreviations: intensity -> radioactivity. Sparsely ionizing radiation absorbed slowly and evenly over the whole body is far less harmful than Po-210 in particles of cigarette smoke, where the ionization is intense for just a few cells near the smoke particle.
