which actinide is used in some smoke detectors?
Be careful about buying anything from China due to problems with their jaw crusher equipment. Name brands like Caterpillar and Komatsu are the most reliable. One equipment firm spams Yahoo Answers with fake advertising about crushers. Advertising is not allowed under the Terms of Conditions for this site, so any advertised products are likely junk. If any spam is added to this question, it will be reported and Yahoo will delete the account.
Yes, as I consider it a bit late to read the instructions on the label when you have actually got to put a fire out!!
