Ionizing radiation may cause damage to living tissue by producing free radicals like reactive oxygen species (ROS). ROS can randomly react with lipids, proteins and nucleic acids of cell causing oxidative stress and damage in these macromolecules, leading to pathogenesis of chronic diseases and age related and also cancer. The first line of defense from the damaging effects of ROS is antioxidants, which convert the oxidants to less reactive species. Lycopene (LYC) is an acyclic isomer of beta-carotene. It synthesized by plants or autotrophic bacteria but not by animals. Red fruits and vegetables, including tomatoes, watermelons, pink grapefruits, apricots, pink guavas and papaya contain LYC. This carotenoid has very strong antioxidant properties. The many studies confirm that dietary supplementation with LYC reduces risk of cancers of many organs, but also retard the growth of the tumors. LYC has also chemopreventive effects against other diseases such as cardiovascular disease, osteoporosis, male infertility and inhibits the toxic action of other agents. Numerous in vitro and animal studies showed that LYC may provide protection against damages induced by ionizing radiation. It suggests that supplementation of LYC might be useful in diminishing of negative effect of cancer radiotherapy or in mitigating the effects of possible radiation accidents on human health.

Promieniowanie jonizujące może powodować uszkodzenia żywej tkanki poprzez wytwarzanie wolnych rodników takich jak reaktywne formy tlenu (RFT). RFT mogą przypadkowo wchodzić w reakcję z lipidami, białkami lub kwasami nukleinowymi komórki, powodując stres oksydacyjny i uszkodzenia w tych makrocząsteczkach, co prowadzi do patogenezy chorób przewlekłych i związanych z wiekiem, a także do zachorowania na raka. Pierwsza linia obrony przed szkodliwym działaniem RFT to przeciwutleniacze, które przekształcają utleniacze do form mniej reaktywnych. Likopen (LYC) jest acyklicznym izomerem beta-karotenu. Jest on syntetyzowany przez rośliny i bakterie autotroficzne, ale nie przez zwierzęta. Czerwone owoce i warzywa, w tym pomidory, arbuzy, różowe grejpfruty, morele, papaja i różowe guawy zawierają LYC. Ten karotenoid ma bardzo silne właściwości antyoksydacyjne. Liczne badania potwierdzają, że suplementacja LYC zmniejsza ryzyko raka wielu narządów, a także opóźnia wzrost guza. LYC ma działanie zapobiegawcze również przeciwko innym chorobom, takim jak choroby układu krążenia, osteoporoza, niepłodność, oraz hamuje toksyczne działanie innych czynników. Badania in vitro i nad zwierzętami wykazały, że LYC może zapewnić ochronę przed uszkodzeniami indukowanymi przez promieniowanie jonizujące. Sugeruje to, że suplementacja LYC może być przydatna w zmniejszaniu negatywnego wpływu radioterapii na zdrowie człowieka lub w łagodzeniu skutków ewentualnych wypadków radiacyjnych.
