Post-acute, long-term impact: Added cancer info; will add a section on subclinical impacts next (unless someone beats me to it)

Better source for predicted deaths. The actual report link has been claimed by link rot, but this information is extremely widespread and can be tracked down elsewhere later.
Line 24:
Following the reactor explosion, which killed two engineers and severely burned two more, a massive emergency operation to put out the fire, stabilize the reactor, and clean up the ejected radioactive material began. During the immediate emergency response, 237 workers were hospitalized, of which 134 exhibited symptoms of [[acute radiation syndrome]]. Among those hospitalized, 28 died within the following three months, all of whom were hospitalized for ARS. In the following 10 years,14 more workers (9 who had been hospitalized with ARS) died of various causes mostly unrelated to radiation exposure.<ref name=":5">{{Cite journal |last=Wagemaker |first=G. |last2=Guskova |first2=A.K. |last3=Bebeshko |first3=V.G. |last4=Griffiths |first4=N.M. |last5=Krishenko |first5=N.A. |date=1996 |title=CLINICALLY OBSERVED EFFECTS IN INDIVIDUALS EXPOSED TO RADIATION AS A RESULT OF THE CHERNOBYL ACCIDENT |journal=One Decade After Chernobyl: Summing up the Consequences of the Accident, Proceedings of an International Conference, Vienna. |pages=173-198}}</ref>

Following the disaster, Pripyat was replaced by the new purpose built city of [[Slavutych]]. The USSR built the protective [[Chernobyl Nuclear Power Plant sarcophagus]] by December 1986. It reduced the spread of [[radioactive contamination]] from the wreckage and protected it from weathering. It also provided [[radiological protection]] for the crews of the undamaged reactors at the site, which were restarted in late 1986 and 1987. However, this containment structure was only intended to last for 30 years, and required considerable reinforcement in the early 2000s. The Shelter was supplemented in 2017 by the [[Chernobyl New Safe Confinement]] which was constructed around the old structure. This larger enclosure aims to enable the removal of both the sarcophagus and the reactor debris while containing the radioactive materials inside. Clean-up is scheduled for completion by 2065.<ref>{{cite news|url=http://www.kyivpost.com/news/nation/detail/56391/|title=Chernobyl nuclear power plant site to be cleared by 2065|newspaper=Kyiv Post|date=3 January 2010|archive-url=https://web.archive.org/web/20121005150746/http://www.kyivpost.com/content/ukraine/chornobyl-nuclear-power-plant-site-to-be-cleared-b-56391.html|archive-date=5 October 2012 }}</ref>
