Stralingsdeskundigheid P3/P4
Periode 3
K = alle overgedragen energie (kerma)
D = alle geabsorbeerde energie (dosis) ->> D = K * (1-g) g=remstraling

Herhaling periode 1/2:




Geabsorbeerde dosis geen goede maat voor alles, want:
- Verschil in biologische werkzaamheid verschillende straling
->> ioniserend vermogen verschilt per soort straling
- Verschil stralingsgevoeligheid verschilt per orgaan
- Sprake van ongelijke dosisverdeling over organen

Equivalente dosis (H) = H=D∗Wr H= Sv, D=dosis in Gy, Wr= stralingsweegfactor (ICRP)
H
->> equivalent dosistempo = Ḣ= in Sv/s
t
->> voor alle verschillende soorten straling en alle weefsels

Effectieve dosis (E) = E=Σ Ht∗Wt Ht= eq. dosis per lichaamsweefsel in Sv, Wt= tissue
weighting factor (ICRP)

E=Σ wt∗Σwr∗D t Ewt = weefselweegfactor, Ewr= stralingsweegfactor,
Dt=gem. orgaandosis
E
->> effectief dosistempo = Ė= in Sv/s
t

 Keten van ionisatie meting = exposie meten -> kerma/geab.dosis -> eq. dosis -> eff. Dosis

Effectieve volgdosis (Ex) = wat patiënt gedurende een jaar ontvangt bij eenmalige inname van
bepaalde activiteit – volwassene E50, kind E70-leeftijd kind
->> afhankelijk van fysische eigenschappen radionuclide, uitgezonden straling, metabool
gedrag van stof, anatomie/metabool gedrag menselijk lichaam en radiobiologische van
gegevens bestraalde organen

E 50=e 50∗Ain E50= eff. volgdosis in Sv, Ain= hoev. inname rad. stof in Bq
