Using the radio-sonde technique, three high altitude balloon flights were made at New Delhi 19° N. (Mag.) to measure the total vertical intensity to heights upto 40,000 feet (200 mb.). It has been found that the intensity

High-altitude balloon flight experiments were conducted at Poona 9° N. (mag.) to measure cosmic-ray intensity with quadruple-coincidence counter telescopes with 10 cm. of lead between the counters, using the radiosonde technique. Heights of 60,000 ft. (100mb.) were reached. It is concluded that the intensity of cosmic radiation penetrating 10 cm. of lead absorber increases monotonically with decreasing atmospheric pressure.

Balloons, upto two million cubic feet in volume, made out of locally extruded polyethylene film ·0011 inches thick, have been successfully flown and altitudes of upto 120,000 ft. attained. Instrumented pay-loads upto 100 kg. in weight have been floated at level ceilings around these altitudes. Various aspects, (such as balloon material, shape and design, and launching methods), which relate to the technique of flying polyethylene balloons of large volume over tropical latitudes are briefly discussed.
