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)[reply]

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)[reply]

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)[reply]

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

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)[reply]

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)[reply]

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)[reply]
