A scheme for modeling tracks of recoil nuclei from elastic scattering of hypothetical dark-matter weakly interacting massive particles (WIMPs) is presented. Constraints on the possibility of directional detection of WIMPs in experiments where light hydrogen nuclei and groups of C, N, and O nuclei, as well as fluorine nuclei, play the role of a target in the detector used are set. The number of WIMPs interactions per unit mass of the detector was estimated by means of the micrOMEGAs software package for an inert doublet model. It is concluded that, for the purpose of visualizing tracks of recoil nuclei and, accordingly, accomplishing a directional detection of WIMPs with lowest assumed masses of 4 to 10 GeV, preference should be given to target of lower density.
