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.

Question: Carl Dean Wilson (December 21, 1946 - February 6, 1998) was an American musician, singer, and songwriter who co-founded the Beach Boys. He is best remembered as their lead guitarist, as the youngest brother of bandmates Brian and Dennis Wilson, and as the group's de facto leader in the early 1970s. He was also the band's musical director on stage from 1965 until his death. Influenced by the guitar playing of Chuck Berry and the Ventures, Carl's initial role in the group was that of lead guitarist and backing vocals, but he performed lead vocals on several of their later hits, including "God Only Knows" (1966), "Good Vibrations" (1966), and "Kokomo" (1988).

A cigarette smoker since the age of 13, Carl was diagnosed with lung cancer after becoming ill at his vacation home in Hawaii, in early 1997. Despite his illness, Carl continued to perform while undergoing chemotherapy. He played and sang throughout the Beach Boys' entire summer tour which ended in the fall of 1997. During the performances, he sat on a stool, but he stood while singing "God Only Knows".  Carl died of lung cancer in Los Angeles, surrounded by his family, on February 6, 1998, just two months after the death of his mother, Audree Wilson. He was interred at Westwood Village Memorial Park Cemetery in Los Angeles.  The Beckley-Lamm-Wilson album, Like a Brother, was finally released in 2000, and Carl's late recordings continue to appear. Brian's album Gettin' in Over My Head (2004) features Carl's vocal from the unreleased Beach Boys song "Soul Searchin'", with new backing vocals recorded by Brian. The original Beach Boys version, sourced from a cancelled attempt at a new Beach Boys album in late 1995, was eventually released in the Made in California (2013) box set, along with another 1995 track titled "You're Still a Mystery", which features Carl in the vocal blend. In 2010, bandmate Al Jardine released his first solo album, A Postcard From California, which includes a similarly reconstructed track, "Don't Fight The Sea", featuring one of the last vocals Carl recorded. Carl can also be heard on the continual stream of Beach Boys archival releases, most notably as a central voice in the November 2011 release of The Smile Sessions.  It was announced that Wilson's voice would be heard on a track from the reunited Beach Boys, on the album That's Why God Made the Radio (2012), but this never materialized. Instead, the scheduled song, "Waves of Love", featured on the 2012 re-release of Jardine's A Postcard From California. During The Beach Boys 50th Anniversary Reunion Tour, a segment of the show was dedicated to the memories of Dennis and Carl. The band harmonized with isolated vocal tracks of Carl performing "God Only Knows" and of Dennis singing "Forever", as the band's crew projected images of the individual Wilson brothers on a large screen behind the band onstage.
