Problem: Background: Slotin was the first of three children born to Israel and Sonia Slotin, Yiddish-speaking refugees who had fled the pogroms of Russia to Winnipeg, Manitoba. He grew up in the North End neighborhood of Winnipeg, an area with a large concentration of Eastern European immigrants. From his early days at Machray Elementary School through his teenage years at St. John's High School, Slotin was academically exceptional. His younger brother, Sam, later remarked that his brother "had an extreme intensity that enabled him to study long hours."
Context: The radiation doses received in these two accidents are not known with any semblance of accuracy. A large part of the dose was due to neutron radiation, which could not be measured by dosimetry equipment of the day. The available equipment, film badges, were not worn by personnel during the accident, and badges that were supposed to be planted under tables in case of disasters like these were not found. Disaster badges hung on the walls did provide some useful data about gamma radiation. A "tentative" estimate of the doses involved was made in 1948, based on dozens of assumptions, some of which are now known to be grossly incorrect. In the absence of personal dosimetry badges, the study authors relied on measurements of sodium activation in the victims' blood and urine samples as their primary source of data. This activation would have been caused by neutron radiation, but they converted all doses to equivalent doses of gamma or X-ray radiation. They concluded that Daghlian and Slotin had probably received doses equivalent to 290 and 880 rem (respectively) of gamma rays. Minimum and maximum estimates varied from about 50% to 200% of these values. The authors also calculated doses equivalent to a mix of soft 80 keV X-rays and gamma rays, which they believed gave a more realistic picture of the exposure than the gamma equivalent. In this model the equivalent X-ray doses were much higher, but would be concentrated in the tissues facing the source, whereas the gamma component penetrated the whole body. Slotin's equivalent dose was estimated to be 1930 R (roentgen) of X-ray with 114 R of gamma, while Daghlian's equivalent dose was estimated to be 480 R of X-ray with 110 R of gamma. Five hundred rem is usually a fatal dose for humans. In modern times dosimetry is done very differently. Equivalent doses would not be reported in roentgen; they would be calculated with different weighting factors, and they are not considered as relevant to acute radiation syndrome as absorbed doses. Recent documents have made various interpretations of Slotin's dose, ranging from 287 rad to 21 sievert. Based on citations and supporting reasoning, the most reliable estimate may be a 1978 Los Alamos memo which suggested 10 Gy(n) + 1.14 Gy(g) for Slotin and 2 Gy(n) + 1.1 Gy(g) for Daghlian. These doses are consistent with the symptoms they experienced.
Question: Anything else pertinent to the dosage?
Answer: A "tentative" estimate of the doses involved was made in 1948, based on dozens of assumptions, some of which are now known to be grossly incorrect.

Problem: Background: Batman is a fictional superhero appearing in American comic books published by DC Comics. The character was created by artist Bob Kane and writer Bill Finger, and first appeared in Detective Comics #27 (1939). Originally named the "Bat-Man", the character is also referred to by such epithets as the Caped Crusader, the Dark Knight, and the World's Greatest Detective.
Context: Batman was one of the few superhero characters to be continuously published as interest in the genre waned during the 1950s. In the story "The Mightiest Team in the World" in Superman #76 (June 1952), Batman teams up with Superman for the first time and the pair discover each other's secret identity. Following the success of this story, World's Finest Comics was revamped so it featured stories starring both heroes together, instead of the separate Batman and Superman features that had been running before. The team-up of the characters was "a financial success in an era when those were few and far between"; this series of stories ran until the book's cancellation in 1986. Batman comics were among those criticized when the comic book industry came under scrutiny with the publication of psychologist Fredric Wertham's book Seduction of the Innocent in 1954. Wertham's thesis was that children imitated crimes committed in comic books, and that these works corrupted the morals of the youth. Wertham criticized Batman comics for their supposed homosexual overtones and argued that Batman and Robin were portrayed as lovers. Wertham's criticisms raised a public outcry during the 1950s, eventually leading to the establishment of the Comics Code Authority, a code that is no longer in use by the comic book industry. The tendency towards a "sunnier Batman" in the postwar years intensified after the introduction of the Comics Code. Scholars have suggested that the characters of Batwoman (in 1956) and the pre-Barbara Gordon Bat-Girl (in 1961) were introduced in part to refute the allegation that Batman and Robin were gay, and the stories took on a campier, lighter feel. In the late 1950s, Batman stories gradually became more science fiction-oriented, an attempt at mimicking the success of other DC characters that had dabbled in the genre. New characters such as Batwoman, Ace the Bat-Hound, and Bat-Mite were introduced. Batman's adventures often involved odd transformations or bizarre space aliens. In 1960, Batman debuted as a member of the Justice League of America in The Brave and the Bold #28 (Feb. 1960), and went on to appear in several Justice League comic series starting later that same year.
