Passage: After completing his primary and secondary education at the Lycée Français in Madrid, Kubrat studied between 1984 and 1990 at the University of Navarra in Pamplona, where he obtained a Licentiate in Medicine and Surgery. After his graduation, he worked for five years as a resident physician at Puerta de Hierro Clinic in Madrid, where he made his expertise as a general surgeon. Subsequently he worked for a year at the St Mark's Hospital and Northwick Park Hospital and further specialized as a surgeon in proctology. Kubrat worked between 1997 and 2003 as a colorectal surgeon at the Ruber International Clinic in Madrid and was in charge of the Ambulatory Surgery Unit. Since September 2003, he became Head of the Colorectal Unit at the San Camillo Hospital in Madrid, where he also acts as Director of the Team Care Management since June 2006. He was director of Shared Medical Systems between 1999 and 2000, and is currently also part of the advisory board of Tokuda Hospital (Sofia, Bulgaria) and a Consultant for Mensor Health Care, S.L in Madrid.

question:
Passage: Over his next three games, Capra went 2-0, with a 1.00 ERA. He allowed just three walks, while striking out fifteen, and began a Braves-record streak of 26 innings pitched without allowing an earned run. Over the month of June, Capra went 6-0 with a 1.05 ERA, three shutouts, and another complete game, to set a team record with nine consecutive wins, on his way to earning NL Player of the Month honors, and selection to the NL All-Star team by his former manager with the Mets, Yogi Berra. (He did not make an appearance in the game.) Capra cooled off during July and August (3-5, 4.43 ERA), but reverted to form in September, to end the season with a major league-best 2.28 ERA, 0.10 better than teammate, Phil Niekro (who finished second in the NL), and .21 better than American League (AL) leader, Catfish Hunter of the Oakland A’s. He also held opposing batters to an NL-leading .208 batting average against (BAA).
 Link Information: Philip Henry Niekro (pronounced NEE-kro) (born April 1, 1939) Answer: Phil Niekro

answer:
Which of the pitchers whose ERAs were worse than Capra's was older?


question:
Passage: Natural strontium is a mixture of four stable isotopes: Sr, Sr, Sr, and Sr. Their abundance increases with increasing mass number and the heaviest, Sr, makes up about 82.6% of all natural strontium, though the abundance varies due to the production of radiogenic Sr as the daughter of long-lived beta-decaying Rb. Of the unstable isotopes, the primary decay mode of the isotopes lighter than Sr is electron capture or positron emission to isotopes of rubidium, and that of the isotopes heavier than Sr is electron emission to isotopes of yttrium. Of special note are Sr and Sr. The former has a half-life of 50.6 days and is used to treat bone cancer due to strontium's chemical similarity and hence ability to replace calcium. While Sr (half-life 28.90 years) has been used similarly, it is also an isotope of concern in fallout from nuclear weapons and nuclear accidents due to its production as a fission product. Its presence in bones can cause bone cancer, cancer of nearby tissues, and leukemia. The 1986 Chernobyl nuclear accident contaminated about 30,000 km with greater than 10 kBq/m with Sr, which accounts for 5% of the core inventory of Sr.
 Link Information: In the accident's aftermath, 237 people suffered from acute radiation sickness, of whom 31 died within the first three months. Answer: it is roughly estimated that cancer deaths caused by Chernobyl may reach a total of about 4,000
answer:

How many people died in the incident that contaminated about 30,000 km?
