Talk:Beta particle

From Wikipedia, the free encyclopedia

The article says, "Beta particles may be stopped by a few milimeters of aluminium. A beta particle's flight is ten times farther than an alpha particle, as it ionizes a tenth less than an alpha particle." 'A tenth less than' is equivalent to saying '90 percent as much as'. I suspect that the intended meaning was 'a tenth as much as'. Can someone who knows a whit about physics confirm this? --Jtoomim 02:18, 1 January 2006 (UTC)


how does a neutron split up in beta- radiation?--219.65.21.133 16:03, 28 Oct 2004 (UTC)

[edit] Tidy up etc

I thought that the first line should refer to 'Beta particles' as this is the title of the article, and then went on to tidy a few things up.

I thought the paragraph about electron guns being a source of beta radiation should be removed. This is because, strictly speaking, beta radiation originates in the nucleus of an atom, whereas the electrons used in a television are produced from an electron gun - it's not the same thing!

The entire Health section could be reworded in my opinion, to provide a more cohesive flow. Bform (talk) 03:18, 28 January 2008 (UTC)

[edit] This sentence needs help

"It does this by converting one of the two up quarks in the proton into a down quark, leaving two down quarks and one up quark (a Neutron) to convert an up quark into a down quark a -1 charge is carried away to observe charge conservation (the W- boson, then the electron, as an up quark carries a charge of +2/3 and the down quark has a charge of -1/3; this quark is said to have undergone a flavor change)" This sentence (which is actually multiple fragments) has 81 words, and is incomprehensible to me!

Alas, my physics isn't up to the task, but yes, it's competely unreadable. Tannin 13:50, 18 May 2006 (UTC)
I tried to clean up that sentence; hopefully it is more comprehensible now. I also added a subsection on inverse beta decay. Heather 19:26, 24 September 2006 (UTC)

[edit] Inverse beta decay

"where a proton is converted into a neutral pion (AKA pi-meson), a positron and an electron-type neutrino:" should read "where a proton is converted into a neutron, a positron and an electron-type neutrino:" Aoosten 22:25, 9 June 2007 (UTC)

[edit] References

References are outdated and new ones are needed. —Preceding unsigned comment added by 24.203.45.90 (talk) 18:14, 6 October 2007 (UTC)

[edit] Merging to Beta decay?

Only the lead paragraph talks specifically about beta particles and beta-radiation. The majority of the article is about the two forms of beta-decay, which are already treated in much greater detail in the dedicated article. It does make sense to have an article specifically on beta particles, but then it should concentrate on things like penetrative power, biological effects, applications, etc. Hqb (talk) 10:02, 13 January 2008 (UTC)

Actually, it looks like the article did contain such material in the past, but it was edited out; I have restored some of it. I withdraw the merge proposal, but the article should still be fleshed out. Hqb (talk) 10:11, 13 January 2008 (UTC)
