We probe roles of blackbody friction forces (BBFFs) in slowing down alkali atoms, from Li through Fr, for high-precision measurements. An atom can encounter BBFF caused by the blackbody. We probe roles of blackbody friction radiations of the stray electromagnetic fields present in experimental set-up and other metallic shielding during measurements. Strengths of BBFFs on the alkali atoms are estimated by integrating complex parts of dynamic polarizabilities of atoms over a wide range of frequency. Slowdown times of moving atoms due to these friction forces are analysed as a function of temperature. The results are determined by both including and excluding nonresonant contributions in the polarizabilities of atomic states. This shows that inclusion of nonresonant contributions affects the slowdown time of atoms significantly at low temperatures. Our study will be useful in accounting for these slowdown times in the ongoing and future high-precision experiments involving alkali atoms.
