input: 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.

Answer this question "Are there acceptable dosages?"
output: Five hundred rem is usually a fatal dose for humans.

Question: Tenacious D is an American rock duo that was formed in Los Angeles, California in 1994. Composed of lead vocalist and guitarist Jack Black and lead guitarist and vocalist Kyle Gass, the band has released three albums - Tenacious D (2001), The Pick of Destiny (2006) and Rize of the Fenix (2012). Tenacious D's studio releases, and (as of 2006) its live performances, feature a full band lineup, including such musicians as guitarist John Konesky and bassist John Spiker. Drummer Dave Grohl (Foo Fighters, Nirvana) has played on every studio album.

Jack Black and Kyle Gass initially met in Los Angeles in 1985, both members of the theatre troupe, The Actors' Gang. Black admits the duo did not see eye to eye due to animosity between the two, as Gass was the main musician for the Actor's Gang and felt threatened by Black. The Actor's Gang travelled to Edinburgh, Scotland for the Edinburgh Fringe in 1989. They were performing Tim Robbins' and Adam Simon's play Carnage. The two became friends during the trip, and eventually became best friends, with Black regularly visiting Gass' Cochran Avenue studio apartment, in the deal that Gass would teach Black to play guitar in return for food, mainly from fast-food chain Jack in the Box. Between 1989 and 1994, the two would work at The Actor's Gang together, and would collaborate in productions. Gass and Black wrote their first song in 1994 after Black had been dumped by a girlfriend, this song was scrapped aside from the pair playing it at later Tenacious D concerts as a joke and referencing it in interviews. Their second song came about when Black was listening to Metallica's "One" in 1994 and told Gass that it was the "best song in the world". Gass told Black that they couldn't write the best song in the world but Black put a twist on it and said they could write a tribute. Gass played an A minor chord at his apartment and the two spent three full days crafting the song, when it was done Gass mentioned "they knew they had something". The song made the duo realise their comedic potential. At their first concert, at Al's Bar (now an apartment complex), the band performed the live debut of "Tribute", their only song at the time, and the duo also gave the audience the chance to vote for their name. Black and Gass gave them the choice between "Pets or Meat", "Balboa's Biblical Theatre" and "The Axe Lords Featuring Gorgazon's Mischief" (Gass' personal favorite). "Tenacious D"--a basketball term used by commentators to describe robust defensive positioning in basketball --did not get the majority of votes, however, but according to Black "we forced it through". The venue had become a hotbed for upcoming bands due to the success of Nirvana and the Red Hot Chili Peppers, so much so that in attendance was David Cross who later cast Jack Black in his sketch comedy television series, Mr. Show. In 1995, the band supported the band, Tool, during their Californian leg. Black attended UCLA with director Jason Bloom, therefore, when Bloom was made the director of 1996's Bio-Dome, Black and Gass were invited to perform a short song in the film. The two wrote the song, "5 Needs", and this was their first on-screen appearance as Tenacious D. Black and Gass also performed their song "Jesus Ranch" in the 1998 film, Bongwater. Tenacious D recorded their songs "Tribute", "Kyle Quit the Band", "Krishna" and "History" and released them in a demo tape called Tenacious Demo, in the mid-1990s with Andrew Gross, distributing it to various record companies until HBO offered them a TV show based upon the tape and Black's work on Mr. Show.
