P. 4559. A pen dosimeter, which contains 5 cm3 air at standard conditions, and which has a capacitance of 1 pF, is charged to 1000 V, initially. What is the absorbed doze, if after the exposure, the voltage drops to 900 V? The average ionization-energy of air is 6.88 aJ and its density is 1.3 kg/m3.
