Micro effect of ionising radiation interaction - Coggle Diagram
Micro effect of ionising radiation interaction
Ionization
direct
DNA Damage
Double strand break :red_cross:
single strand break :fire:
Indirect
Interaction with H20:Radiolysis
Ion Produce: H2O -> H2O+ + e-
e- combined with H2O: e- + H2O -> H20-
Free Radical Interect:
OH^ + OH^ -> H2O2 (Hydorgen Pyroxide)
radical combinations: H^ + H^ -> H2
OH^ + H^ -> H2O
Other Interactions
H2O + e- -> H^ + OH-
H2O+ + H2O -> H3O+ + OH+
H3O+ + e- -> H^ + H2O
H^ + O2 -> H2O^
Ionic Molecule Dissociates: H2O+ -> H+ + OH^
Interaction with protein
base : Amine (NH2) , Carboxyl (COOH) &Side chain R
Damage happen at side chain R
100 Gy to see the effect
Physical change : Viscocity , Conductivity
Interaction with carbohydrates
Interaction with enzymes
As catalyst for biochemical process
It can be non reactive
400 Gy to see the effects
Reactivity effects can be stopped or reduce with the substrate of enzyme
interaction with nucleic acid
