This document discusses several case studies related to radiation: - Reports of increased radiation levels around Chernobyl, Ukraine following the Russian invasion and occupation of the area. - Concerns about radiation safety after Russian forces seized a nuclear power plant in Ukraine. - Studies on the use of radiation in medical treatments like breast cancer radiotherapy and warnings against unnecessary radiation exposure, especially in children. - Development of anti-radiation missiles and fungi that could help protect astronauts from radiation in space.

2. What is radiation
✦ Radiation is energy that comes from a source
and travels through space at the speed of
light.
✦ This energy has an electric field and a magnetic
field associated with it, and has wave-like
properties. You could also call radiation
“electromagnetic waves”.

✦ High levels of radiation reported from
Chernobyl in Ukraine
✦ A nuclear reactor at Chernobyl, 67 miles
(108 km) north of the Ukrainian capital
Kyiv, exploded in April 1986 during a
botched safety test, sending clouds of
radiation billowing across much of
Europe and reaching the eastern United
States.

✦ Russia's seizure of Ukraine nuclear plant
adds to fears about radiation safety
✦ Russian forces captured the Zaporizhzhia
plant - Europe's largest - after attacking it in
the early hours of Friday, setting an adjacent
five-storey training facility on fire,
Ukrainian authorities said. The International
Atomic Energy Agency (IAEA) said in a
tweet Ukrainian authorities had informed
the agency that the fire at the site had not
affected "essential" equipment.

children should not be exposed to
radiation, unnecessary medications
✦ As the third wave of the COVID
pandemic raises concern of infection
among children, an expert has suggested
that there is no need to panic as the
Omicron, Variant of Concern, is mild,
but have asked to avoid unnecessary
medications and radiation exposure.

successfully test fired a new generation anti-
radiation missile which will be part of the
tactical weaponry of the Indian Air Force,
officials said. The missile, Rudram-1, is India's
first indigenously developed anti-radiation
missile that has a speed of Mach two or twice the
speed of sound.

✦ In situ radiometric survey carried out in
81 revenue villages of Kanyakumari
District, Tamil Nadu, India, using a
portable radiation dosemeter/detector,
revealed the existence of radiation
hotspots along the coastal belt.
✦ A close observation of the coastal

25. Case studies
✦ A very high intrinsic anomalous
radioactivity of 41.03 μSv h(-1) was
observed, in a famous tourist spot in the
coastal belt of Kanyakumari District.
✦ This is the highest level of radiation
registered in South India, which is
extremely higher than the permissible
world average and is suggestive of
causing severe clinical problems on
continuous and prolonged exposure
