Talk:Counts per minute

Detector efficiency
You do not discuss/mention the EFFICIENCY of the detector, which relates cpm to dpm. Please update.19:12, 25 February 2008 (UTC)19:12, 25 February 2008 (UTC)mcconne6@msu.edu69.208.241.156 (talk) 19:12, 25 February 2008 (UTC)
 * In the section Counts_per_minute there is a short discussion on (and link to) counting efficiency, as of February 2015, thanks to User:Dougsim. —Hulten (talk) 13:08, 17 April 2015 (UTC)

Move discussion in progress
There is a move discussion in progress on Talk:Kilometres per hour which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 00:59, 10 December 2013 (UTC)
 * Just to disambiguate the title (that contains a compound noun): this relates only to the name of the article (so a discussion on the potential move of the article, not the discussion itself). —Hulten (talk) 13:08, 17 April 2015 (UTC)

Comparison with other units
The section Counts_per_minute compares Bq with cpm. While the mention of Bq is imperative, the comparison should be between dpm and cpm. I could change this and clarify that paragraph, if I understand it correctly: Bq and dpm are decays per unit of time (difference is a factor of 60 seconds per minute), while cpm tends to measure dpm, but depends on the counting efficiency. Correct? —Hulten (talk) 13:08, 17 April 2015 (UTC)


 * Yes there could be improved clarity there. Bq would best be compared with disintegrations per second and cps. Just have to make sure difference between events at the source and events at the detector are still clearly differentiated. Dougsim (talk) 03:23, 18 April 2015 (UTC)


 * I have made minor changes. I reduced the switching between disintegrations and counts in the concerning paragraph, which should make it read more easily.
