The internal conversion coefficients (ICC) have served formany years as an indispensable tool to assign the spin-parity quantum numbers of excited nuclear levels. There existwidely distributed tables /1-3/ of ICC covering broad regions of transition energies, atomic numbers from Z = 30/1,3/or 10/2/ up to Z = 103/3/ or Z = 104 /1,2/ and transition multipolarities M1-M4, E1-E4. Very recently, tables of ICC for the superheavy elements (104 ó Z ó 126) appeared /4/.When computing ICC, however, various approximations are applied. Some of them are of purely theoretical origin, e.g.the calculations are done only for the first non-vanishingorder of the perturbation theory. Others are connected withan improper description of physical reality, e.g. the ICC iscalculated for a free atom, whereas the real source atom isusually chemically bound in some coompound or embedded within a solid. In this work we systematize these particular sources of uncertainties and estimate their effect on the accuracy of the calculated ICC.
