The German midfielder, captain of the side that won the World Cup of 1990, was the first FIFA World Player of the Year when the award began in 1991; FIFA gave it until 2015, with the Ballon d’Or years of 2010 to 2015 in between, and replaced it with The…

The International Cricket Council began its annual awards in 2004, and the cricketer of the year receives the trophy named after the great all-rounder of the West Indies; the first winner was Rahul Dravid of India, and Sachin Tendulkar, Ravichandran Ashwin and Virat Kohli have also received it.

France Football and FIFA joined their two awards into one for those six years, so the winner of each of those years holds the FIFA Ballon d’Or; the partnership ended and the two awards were given separately again from 2016, when FIFA began The Best FIFA Men’s Player.

The women’s award was introduced in 2018, more than sixty years after the men’s, and the Norwegian forward, then with Lyon, was its first winner.

The Kopa Trophy was introduced in 2018 and is named after Raymond Kopa, the French forward who won the Ballon d’Or in 1958; its first winner was Kylian Mbappe of France.

Lev Yashin of the Soviet Union, known as the black spider for his dark jersey and his reach, won the Ballon d’Or in 1963, and no other goalkeeper has taken it since, which is why the trophy for the best goalkeeper of the year, given from 2019, is named the…

The English winger, then playing for Blackpool and already past forty, received the first Ballon d’Or in 1956, at a time when only European players could be considered.

The French magazine France Football created the Ballon d’Or in 1956 on the idea of its editor Gabriel Hanot, and the winner is settled on the votes of journalists, which is what separates it from an award given by a federation.

The award went to the scene after India won the World Cup of 2011, when the younger players carried Sachin Tendulkar on their shoulders around the Wankhede ground; the Best Sporting Moment is the one Laureus award decided by a public vote, which is why the Indian following mattered.

The first President of a democratic South Africa was the patron of the Laureus awards, and at the opening ceremony in 2000 he said that sport has the power to change the world and to unite people in a way that little else does; the sentence is now printed with…

The awards were established in 1999 by the founders of the Laureus Sport for Good Foundation, and the first ceremony took place in 2000 at Monte Carlo in Monaco, where Nelson Mandela, the patron of the awards, said that sport has the power to change the world.

A Geiger-Muller counter contains a gas-filled tube in which an entering ray ionises the gas and sets off a pulse of current, so each pulse counts one particle; a film badge worn by a worker records the total dose instead.

Iodine-131 has a half-life of roughly eight days, which is why the danger from it after an accident is intense but short-lived, and why potassium iodide tablets are distributed at once so that the thyroid gland is saturated with ordinary iodine and absorbs less of the radioactive form.

Reactor number four of the Chernobyl plant, in Ukraine in the then Soviet Union, exploded on 26 April 1986 and scattered radioactive iodine, caesium and strontium over a wide area of Europe.

The becquerel, symbol Bq, is the SI unit of activity and equals one disintegration per second.

Strontium lies just below calcium in the same group of the periodic table and behaves chemically like it, so strontium-90 taken in through milk, water or food is deposited in bone and in teeth in place of calcium.

A cooling tower releases the heat of used cooling water to the atmosphere by evaporation or by air flow, so that the water leaving the plant is close to the temperature of the receiving river or lake.

Thermal and nuclear power stations draw large volumes of water to condense steam and return it several degrees warmer, which makes them the single largest source of waste heat in rivers, lakes and coastal waters.

The solubility of a gas in water decreases as the temperature of the water rises, so hot water discharged from a power station holds less dissolved oxygen.
