Chlorine-36-tagged chloroform, CHCl3, whose specific activity is 100 μCi/mol, is to be used under such conditions that 100 mg/h may be lost by evaporation. The experiment is to be done in a laboratory of dimensions 15 ft × 10 ft × 8 ft. The laboratory is ventilated at a rate of 100 ft3/min. Do any special measures have to be taken in order to control the atmospheric concentration of 36Cl to 10% of its dac (DAC=1E-6uci/cm3)

a) Yes, special measures are required to control the atmospheric concentration of 36Cl.
b) No, special measures are not required as the atmospheric concentration of 36Cl is already within the acceptable limit.
c) Special measures may or may not be required depending on the specific experimental setup.
d) The information provided is insufficient to determine the need for special measures.
