Talk:Caesium-137

How much cesium in the environment and in air?

Any estimates for a total amount of uncontained cesium-137 in atmosphere, and in water+soil? Would it be few grams in air and few kilograms in soil and water? More? Less? 85.195.241.133 (talk) 21:05, 27 January 2023 (UTC)

I understand your question but please explain the parameters you are working off x Sean 82.17.71.122 (talk) 23:18, 2 June 2023 (UTC)

Anything but metric units?

The image on this page captioned "A sealed caesium-137 radioactive source" offers no indication of what scale the rule adjacent to the source indicates. Feet, inches, olympic washing machines? A statement of scale would improve things. 125.168.39.55 (talk) 12:39, 20 July 2023 (UTC)

It's inches, as noted by the 1/2, 1/4, and 1/8 markings. Rickane58 (talk) 03:59, 2 June 2024 (UTC)

Decay mode

The properties box contradicts the prose text. The box lists two decay modes, one beta, one gamma. The text clearly states that the gamma radiation comes from Ba-137m. That would mean the listed gamma decay mode is none of Ce-137. A mistake in the text is also possible, though. What is correct? WikiPidi (talk) 16:03, 29 August 2023 (UTC)

Whenever you talk about radioactive gamma-decay, the emitted gammas are radiated "after the decay" and therefore stem from the daughter. To answer your question: Both is correct! 134.95.217.15 (talk) 12:15, 30 September 2024 (UTC)

Environmental contamination (Cs-137 half-life)

The box at the top states a different (30.05 y) half-life than the box in the section "Environmental contamination" (30.23 y). What is correct resp. where are the according sources and literature?! 134.95.217.15 (talk) 12:20, 30 September 2024 (UTC)
