Premixed, commercially available scintillation fluids were used to reduce exposure time of tritium (/sup 3/H) and iodine-125 (/sup 125/I)-labeled whole cells, and of /sup 3/H-labeled Giemsa-banded chromosome preparations. Emulsion-coated slides were dipped into scintillator for no longer than 2 min and exposed in the dark at 4 degrees C. Maximal values for percentage of human diploid cell (WI-38) nuclei labeled with /sup 3/H-thymidine of moderate specific activity were obtained in 12 h. Without scintillator the exposure time was 4 days. Exposure time for cells labeled with /sup 125/I-serum was reduced from over 90 days to 14 days. The shortened exposure time for banded chromosomes permitted successful prestaining with Giemsa, a sequence that is not possible without scintillator.
