ISO 361?

Does any know whether this is the symbol described in ISO 361? If it is, it would be helpful for the description to say so explicitly. Mitch Ames (talk) 09:26, 27 August 2011 (UTC)
Not just Radioactivity warning sign
[編集]
The usual yellow warning sign is actually NOT just a warning sign of radioactivity. It is a warning sign of Ionizing Radiation.
Ionizing radiation is a much broader category than just radioactivity. It is also caused by particle accelerators and medical equipment such as x-ray scanners or beam-cannons for example. It is true that radioactive radiation is (usually) also ionizing, but it is just a sub-group.
The categorization of this image (and many many others unfortunately) should therefore be changed accordingly. There are however international work in progress to introduce a new red warning sign of Ionizing radiation, so perhaps a bit of this sad mess will be easier to handle in the future. See here: [1]
