beta particle example

The electron, however, occupies regions outside the nucleus of an atom. A beta particle is given a mass number of zero because the Such contamination presents a hazard because of the radioactive decay of the contaminants, which emit harmful ionising radiation such as alpha particles or beta particles, gamma rays or neutrons. }] bids: [{ bidder: 'rubicon', params: { accountId: '17282', siteId: '162050', zoneId: '776346', position: 'btf' }}, {code: 'ad_contentslot_3', pubstack: { adUnitName: 'cdo_mpuslot', adUnitPath: '/2863368/mpuslot' }, mediaTypes: { banner: { sizes: [[300, 250], [336, 280]] } }, and in the opposite As can be seen from the image below the beta de… userSync: { Copyright © 2015 gcsescience.com. { bidder: 'pubmatic', params: { publisherId: '158679', adSlot: 'cdo_mpuslot1' }}]}, Exercise 11.3. {code: 'ad_topslot_b', pubstack: { adUnitName: 'cdo_topslot', adUnitPath: '/2863368/topslot' }, mediaTypes: { banner: { sizes: [[728, 90]] } }, It emits beta particles of low to medium energy but no gamma rays, so has little hazard on external exposure, but only if ingested.
