Is that true that resistor, inductor and capacitor are non semiconductor devices and they don't have any semiconductor material inside them ?
 
Generally, although in IC design we will find ways to
make "good enough" passives out of the materials at
hand - poly or implanted resistors, MOS or MIM
capacitors, spiral inductors....
 
Every part ehxibit capacitance, inductance and resistence in some extent ( sorry, a general question deserves a general answer ).
Seriously speaking: The equations that govern the operation of any alternating current circuit are the same regardless of how you name such components as Capacitor, Resistor or Inductor, so that, for example, at a high frequency electrolytic capacitor behaves likewise an inductor.
 
But these non semi conductor components "resistor, inductor and capacitor" do not de-grade their performance in radiation environment, right ? as semi conductor based ICs does.
 
not an expert in this subject, but:

it depends on what the component is made of and how much radiation it gets hit with

consider a thin film resistor - enough ionizing radiation can degrade its performance
perhaps also a thick film resistor

capacitors are two (or more) layers of a thin conductor with a dielectric in between
enough ionizing radiation may damage the dielectric, especially thin dielectrics

inductor are (basically) wire wrapped around a magnetic material
enough ionizing radiation to damage an inductor would be the least of the damage to your device
 
Both passive devices (RLC) and active devices (all semi's) can be degraded in insulation by radiation and reduced MTBF.
L types that use magnet wire with silicate insulation are also affected.

Mil-Std-Hdbk-883 will provide reliability exponents for each part to add to the probability of mean failure rate according to each source of environmental stress.

I first used this calculation when it was version 883B. Now it is possibly going towards Z. ;)
These do not include manufacturing or design defects per se nor can you estimate worst case radiation, but there are prediction models for solar and cosmos radiation beyond the 11 yr cycles towards Carrington Effects that may wipe out or disrupt many old satellite designs.

Hi,

what does degrade mean?
The non reversible destructive "degrade",
Or the reversible "getting conductive" by semiconductors? Don´t know if one can nae this "degrade" ... but it surely is a degradation of leakage current.

"Degradation" may be the growth of insulation or oxidation on power connectors or the effective drop in leakage resistance and breakdown voltage (BDV) on insulators.

More details

In some cases high E-field radiation such as 1GV is helpful on cross-linked plastic coated cables and rubber tires to enhance the durability from wear and tear and actually increase the breakdown voltage by detonating the contaminating molecules and aligning the molecular structures. This is how grid cables are made.
