Is it just me or is the example miscalculated? If 1 Ci = 3.7×1010 Bq then why is Ci = 2.22×106 disintegrations per minute??? shouldn't it be 1 Ci = 3.7×104 Bq? FtPeter ( talk) 23:30, 29 April 2009 (UTC)
Why even mention the conversion to the number of disintegrations per minute? Of what relevance is that? Abiermans ( talk) 21:21, 15 December 2009 (UTC)
Changing the name of Curie to "Curie (unit)" or "Curie (Measurement)" would fix this little problem in Wikipedia's mislabel of this. Kenji000 ( talk) 13:35, 17 March 2008 (UTC)
Is the conversion between Ci and Bq defined as exactly 37 billion? If not, then the inverse conversion should certainly not be exact, as indicated by the repeating decimal. Even if it is exact, I feel like it draws attention undue attention and should be removed. Unless someone can argue otherwise, I'll change it.

Should megacurie, kilocurie, etc. have their own pages? I imagine not, unless they have specific examples of levels of each. Otherwise they could be placed on this page, or maybe create an Orders of Magnitude (Radiation) page? Probably not necessary, though. I am retyping some larger orders of magnitude to here for now. (I guess I could have made redirects. Oh well.) Omegatron 19:54, Feb 10, 2004 (UTC)why would we be able to change things like weird!!! i could change everything on wikipedia then yeah!!!!!!1
To find Orders of Magnitude, see:

I currently work in nuclear power and would say that the curie is far from being replaced by any other unit. The curie is still the standard for measure of quantity of radioactive material throughout the US commercial and Naval nuclear power programs.
What exactly is a low, normal and high level of radiation measured in curie? What is a dangerous level for humans? I saw in the series Heroes they measured 1800 Curie and said "let's get out of here". Is that realistic, or would they be dead already?

Shouldn't this be a nuclear physics article, instead of a chemistry article?
This article states that the curie was named after Marie Curie, however, Pierre Curie states that the curie was named after Pierre. 71.238.70.220 ( talk) 00:08, 3 February 2008 (UTC)
I say that megacurie, kilocurie, etc. should have their own pages since kilogram and other measurments have their own pages. Since this is true, why shouldn't the curie measurments have their own pages? —Preceding unsigned comment added by 72.85.252.151 ( talk) 21:37, 2 April 2008 (UTC)
Objective bystander logic: No, because kilograms and kilometers (and millimeters and nanometers etc.) have distinct relevancies. If an article about megacuries is simply "1 million curie" its not worth it. —Preceding unsigned comment added by 67.212.110.120 ( talk) 01:07, 10 April 2008 (UTC)
A kilogram is the base unit in the MKS SI system and so has it's own page. A kilometre is the standard 'everyday' measurement of long distances so it has it's own page, even though it is not a base MKS SI unit - the metre is. In the old (but still used) system from which the Curie comes from, a megacurie or kilocurie is rarely used, unless you are talking about the fallout from a large nuclear weapon. Even a Ci is a big unit and in 'normal' use - in medicine, industry, university etc - then the μCi or mCi (microcurie or millicurie) are usually used.

Non-experts may be curious about the relationship between the two units (if any), just what is measured and which unit is used and why. —Preceding unsigned comment added by 173.13.101.166 ( talk) 20:14, 7 August 2010 (UTC)
What’s the deal with the unit’s symbol? The article uses “Ci”, which is what one would expect for a unit derived from a proper name. But the table in Curie#Radiation Related Quantities uses “c” (a lower-case C), and I’ve seen it like that elsewhere on Wikipedia. Shouldn’t there be a note about alternate usage somewhere in there? bogdanb ( talk) 20:00, 13 March 2014 (UTC)
The Curie is not an SI unit and therefore does not need to conform to SI conventions on capitals and plurals. 78.148.195.135 ( talk) 11:08, 22 April 2015 (UTC)
This article could benefit from a history section, describing when and how this unit came to be and its usage history. This would also be a good place to expand on when and why the NIST started discouraging its use. 50.174.76.122 ( talk) 19:40, 7 April 2015 (UTC)
The result of the move request was: Consensus for the disambiguation page. ( non-admin closure) b uidh e 23:25, 20 June 2020 (UTC)
Curie → Curie (unit) – I doubt the unit of measurement is the primary topic for Curie. I am proposing three options. I support Option 1, but open to other interpretations.
Curie is a disambiguation page with no primary topic.
Curie redirects to Marie Curie with a hatnote pointing to the disambiguation page.
Leave everything as is. Interstellarity ( talk) 18:19, 12 June 2020 (UTC)
