4-H Dancers

Photograph of a group of young girls posing for the camera in front of a curtain backdrop. They are wearing traditional Danish costumes, which consists of a pointed hat with ribbon attachments, a vest-like bodice tied across their bust, and a tied apron over a full skirt with horizontal stripes running across the bottom of the skirt. On the back row, from left to right, the girls have been identified as Jane Laustrup, Neva Bram, Peggy Bram, Sharon Krag, and Annette Waldman. On the front row, from left to right, they have been identified as Carolyn Lauritsen, Sharon Roberts, Beverly Waldman, and Eleanor Berndt. Hand-written text on the back of the photograph lists their names again, and a secondary, upside down blue line of text reads, "Danish Dancers, Return to Lillian Roberts".

"25" Critically Consultation with J. W. Morfitt : April 3, 1950 (open access)

"25" Critically Consultation with J. W. Morfitt : April 3, 1950

Summary: "Criticality was considered impossible in any contingency encountered in practice under either of the following conditions which include no safety factor: (a) In any isolated cylinder not more than 5 in. in disruptor, if the total amount of U235 present does not exceed 7.5 Eg. (b) In an isolated vessel of any shape and size, if the total amount of U235 present does not exceed 880 g. An "isolated" vessel is one which does not "see" more than 0.1 [...] other vessels containing fissionable material."
