Dosimeters measure an individual's or an object's exposure to something in the environment — particularly to a hazard inflicting cumulative impact over long periods of time, or over a lifetime. This article concentrates on the radiation dosimeter, which measures exposure to ionizing radiation, but other dosimeters also exist, such as sound dosimeters, ultraviolet dosimeters, and electromagnetic field dosimeters. Ionizing radiation, such as X-rays, alpha rays, beta rays, and gamma rays, remains undetectable by the senses, and the damage it causes to the body is cumulative, related to the total dose received. Therefore, workers who are exposed to radiation, such as radiographers, nuclear power plant workers, doctors using radiotherapy, workers in laboratories using radionuclides, and some HAZMAT teams are required to wear dosimeters so their employers can keep a record of their exposure, to verify that it is below legally prescribed limits. Crew members aboard NASA Space Shuttle missions have access to four types of active dosimeters should a radiation contingency occur. Crew members are required to wear passive dosimeters at all times throughout the mission. Common types of wearable dosimeters for ionizing radiation include: Quartz fiber dosimeter Film badge dosimeter Thermoluminescent dosimeter Solid state (MOSFET or silicon diode) dosimeter The quartz fiber dosimeters have to be prepared, usually daily, with a positive charge from either a hand-wound or battery-powered charging unit. As the gas in the dosimeter chamber becomes ionized by nuclear radiation the charge leaks away causing the fiber indicator to rise up the graduated scale. Factories prepare film-badge dosimeters for one-time use. The level of radiation absorption is indicated by a change of color on the film badge's surface, which is compared to an indicator chart. Manufacturing processes that treat products with ionizing radiation, such as food irradiation, use dosimeters to calibrate doses. These are different from personal dosimeters because they usually must have a greater range. They often consist of small blocks of material such as perspex. One can also carry out the dosimetry of neutron radiation with a few specialised devices such as superheated drop detectors. The Fukushima I nuclear accidents are a series of ongoing equipment failures and releases of radioactive materials at the Fukushima I Nuclear Power Plant, following the 2011 Tohoku earthquake and tsunami on 11 March 2011. The plant comprises six separate boiling water reactors maintained by the Tokyo Electric Power Company (TEPCO). Reactors 4, 5 and 6 had been shut down prior to the earthquake for planned maintenance. The remaining reactors were shut down automatically after the earthquake, but the subsequent 14 metres (46 ft) tsunami flooded the plant, knocking out emergency generators needed to run pumps which cool and control the reactors. The flooding and earthquake damage prevented assistance being brought from elsewhere. On 20 March, the Japanese government spokesman Yukio Edano announced that the plant would be closed once the crisis was over. From 11 March on, there was evidence of partial core meltdown in reactors 1, 2, and 3; hydrogen explosions destroyed the upper cladding of the buildings housing reactors 1, 3, and 4; an explosion damaged the containment inside reactor 2; and multiple fires broke out at reactor 4. In addition, spent fuel rods stored in spent fuel pools of units 1-4 began to overheat as water levels in the pools dropped. Fears of radiation leaks led to a 20 km (12 mile) radius evacuation around the plant. TEPCO employees and workers from other companies not involved in essential work were temporarily evacuated after an explosion was heard in the suppression chamber of reactor building 2. Employees returned after it was confirmed that there had not been a containment breach but evacuated again on 16 March following a spike in radiation. On 18 March, Japanese officials designated the magnitude of the danger at reactors 1, 2 and 3 at level 5 on the 7 point International Nuclear Event Scale (INES). Many international leaders have expressed concerns about the accidents. The Japanese Government and TEPCO have been criticized for poor communications over the incident. Power was restored to parts of the plant on 20 March, although the condition of the plant machinery was unclear. On 19 March, Japan banned the sale of food raised in the Fukushima area up to 100 km (65 miles) from the damaged facility due to contamination above safe limits.By 23 March, levels of radioactive iodine in Tokyo drinking water were unsafe for infants and the government distributed bottled water Made in: Russia, Moscow, 1991.
