Physics

21 Terms

1

massagetal

protonen + neutronen

New cards
2

lading elektron

e- = 1,6×10^-19 C

New cards
3

nucleon

is 1 kerndeeltje: proton of neutron.

New cards
4

isotopen

atomen van hetzelfde element met verschillende kernmassa’s, veroorzaakt door verschil in aantal neutronen.

New cards
5

atomaire massa-eenheid u

1 u =^1,66054×10^-27 kg

New cards
6

stabiele kernen

aantrekkende kernkrachten tussen nucleonen houden kerndeeltjes bij een. De kern vervalt niet, deze zendt dus geen straling uit.

New cards
7

instabiele kernen

kernen zitten ‘'niet goed’' in elkaar en vervallen tot kernen van een ander element of kernen met een andere groepering van kerndeeltjes of neutronenaantal. Hierbij wordt straling uitgezonden, elektromagnetische straling.

New cards
8

radioactiviteit

verschijnsel dat instabiele atoomkernen α-, β- en/of γ-straling uitzenden, omdat deze kernen vervallen tot kernen met een andere samenstelling of omdat de nucleonen in deze kernen hergroeperen.

New cards
9

elektronvolt eV

eenheid van energie. Wordt vaak gebruikt als eenheid bij de energie van α-, β- en/of γ-straling. 1,0 eV = 1,6×10^-19J.

New cards
10

foton

een ‘‘lichtdeeltje’’ ofwel: een pakketje stralingsenergie.

New cards
11

röntgenstraling

bestaat uit fotonen met veel energie meer dan zichtbaar licht minder dan γ-straling.

New cards
12

hardheid van straling

harde straling bevat fotonen met zeer veel energie, zachte straling bevat fotonen met minder energie.

New cards
13

groot doordringend vermogen
