But would irradiation harm the tobacco? Among Szilard’s surviving papers is lodged a fading letter from Dr. M. Lenz of the Montefiore Hospital for Chronic Diseases that reports the decisive experiment: On April 14, 1938, at 2:30 p.m.907, your six cigars were irradiated with 100 kv., a filter focus distance of 20 cm. with ten minutes in front and ten minutes over the back of each cigar. This gave them 1000 r. in front and 1500 r. in back of each cigar. I hope that your friend finds the taste unchanged.
