在切尔诺贝利受损的核电站（ChNPP）的沉降物后，电离辐射对松树林生存能力的影响在10公里区域内显示出来。 在1986-1991年期间，辐射和受损的林分，所谓的“红色森林”，位于该地区的系统分类的观察。 死亡率，重建，树冠的发展，繁殖异常和立场的可行性被证明是依赖于吸收的辐照剂量，对年龄的立场和森林组成。 对于受严重影响地区的松树林，超过60戈伊的剂量导致了大量死亡，自1987年以来松树没有再生。 受伤的树木要么被烧毁，要么已经干枯。 大量的病原昆虫侵入垂死的树木，加速了干燥过程。 10-60戈伊、1-10戈伊和0.1 ~ 1戈伊的辐照剂量分别对林分造成高、中、低伤害。 低于0.1戈伊的剂量不会对树木造成任何可见的损害。 1987年，树冠显示出修复过程，除严重和高度受影响地区的树木外，几乎所有森林都恢复了生存能力。 幼林被重新建立在同一个地方的死亡树木和新的松树树苗种植在开垦地区。
The effect of ionizing irradiation on the viability of pine stands after the fallout from the damaged nuclear energy plant at Chernobyl (ChNPP) was shown within the territory of the 10-km zone. During the period 1986-1991, irradiated and damaged forest stands, so-called 'red forest', located in this area were systematically classified by observation. Mortality rate, re-establishment, development of tree canopies, reproduction anomalies and stand viability were shown to be dependent on absorbed irradiation dose, on the age of the stand and on forest composition. For pine stands in the acutely affected zone, doses of more than 60 Gy resulted in a massive mortality and no regeneration of pine trees since 1987. The injured trees had burned or had dried-up. The drying process was accelerated by a massive production of pathogenic insects invading the dying trees. Specifically, irradiation doses of 10-60 Gy, 1-10 Gy and 0.1-1 Gy caused high, medium and low injury to the forest stands, respectively. Doses of less than 0.1 Gy did not cause any visible damage to the trees. In 1987, repair processes were displayed by the tree canopies and practically the entire viability of the forest stands had recovered except for trees in the acute and highly affected zones. The young forest was reestablished in the same place as the perished trees and new pine saplings were planted on the reclaimed areas.
