Nature has been smart enough to use several ways to avoid the disadvantageous stopping of energy in the antenna before it reaches its target, i.e. the reaction centre. 
Loodus on teravmeelselt kasutanud mitut võtet vältimaks kahjulikku energia peatumist antennis enne tema sihtmärki, st reakt- sioonitsentrisse jõudmist.
A main one, exciton self- localization we revealed recently. 
Neist üks peamine, eksitonide autolokalisatsioon, õnnestus meil tuvastada alles üsna hiljuti.
In the investigations, having lead to these conclusions the methods of ultrafast spectroscopy (temporal resolution ~ 100 fs) were used in parallel with the means of high resolution spectroscopy (spectral resolution ~ 0.1 cm). 
Nendele järeldustele viinud kompleksuuringutes kasutati ülikiire (ajaline lahutusvõime ~100 fs) spektroskoopia meetodeid kõrvuti kõrglahutusspektro- skoopia (spektraalne lahutusvõime ~0,1 cm) võtetega.

In the field of environmental physics in the Institute (Laboratory of the nuclear spectroscopy) the focus is on the abundance of radioactive substances, their spread and migration in Estonia. 
Keskkonnafüüsika valdkonnas ollakse FIs (tuu- maspektroskoopia laboris) keskendunud radio- aktiivainete koguste, nende leviku ja rände uurimisele Eestis.
In soviet times the local radiation hazards were almost not investigated and the population remained uninformed about the risks. 
Nõukogude ajal siinseid kiirgusohte kuigivõrd ei uuritud ega teavitatud neist rahvast.
At the northern coast of Estonia there are minerals and soils with enhanced radioactivity. 
Meie põhjarannikul leidub kõrgendatud radioaktiivsusega mineraale ja muldi.
The war preparations of the Soviet Union left here a lot of sources of radiation risks (uranium production/enrichment wastes at Sillamäe, extensive nuclear equipment at the training centre of nuclear submariners at Paldiski etc). 
Nõukogude Liidu sõjavalmistused jätsid meile rohkesti kiirgusohu allikaid (Sillamäel uraani tootmise/rikastamise jäätmed, Paldiski tuuma-allveelaevnike õppekeskuse ulatuslikud tuumaseadmed jne).
These power plants are sometimes considered to belong to the greatest pollution sources in Europe. 
Neid jaamu peetakse koguni üheks suuremaks saasteallikaks Euroopas.
By the analysis of soil samples the researchers have got a detailed picture of the spread of radioactivity in the Estonian soils and into depth. 
Aastate kestes on pinnaseproovide uurimise teel saadud üsna selge pilt radioaktiivsuse levikust Eesti maapinnas ja süvitsi.
The obtained data have been introduced into international data banks. 
Saadud andmed on viidud rahvusvahelistesse andmekogudesse.
Investigations are underway of the radioactivity of common building materials, as well as of the most widely used fuels – wood and peat and their ashes. 
Uuritakse ehitiste püstitamisel kasutatud ehitusmaterjalide, samuti kõige laialdasemalt tarvitatavate kütuste – puidu ja turba ning nende tuha radioaktiivsust.
The environment physicists of the Institute have contributed to the assessment of the depositories of the radioactive wastes, the contemporary as well as these planned in the future. 
FI keskkonnafüüsikud on kaasa aidanud ka radioaktiivsete jäätmete hoidlate ohtlikkuse – nii praeguse kui ka tulevase – hindamisel.
The researchers have elucidated that in Estonia there are sites unique for all Europe by their high radium content in soil; 
On selgitatud et Eestis on kogu Euroopa jaoks ainulaadseid kohti raadiumi kõrge sisalduse poolest pinnases;
long term environmental effects of the depository of radioactive wastes at Tammiku; 
Tammiku radioaktiivsete jäätmete hoidla pikaajalisi keskkonnamõjusid;
that the fly ashes of the thermal power plants contaminate soil, water, and air in the environs with a number of radioactive substances, incl. radioactive lead. 
et soojusjõujaamade lendtuhk saastab nende ümbruse pinnast, vett ja õhku mitmete põlevkivis leiduvate kiirgurainetega, sh radioaktiivse pliiga.
We were relatively lucky also during and after the Chernobyl catastrophe, as compared with our northern and western neighbours: the dominating winds were blowing then, and the rains falling, so that they did not carry to us too much of the radiopollution, released from the blown up nuclear plant. 
Suhteliselt hästi, võrreldes näiteks põhja- ja läänepoolsete naabritega, läks meil ka Tšernobõli aatomielektrijaama katastroofi ajal ja järel: valdavad tuuled puhusid ja vihmad sada- sid tollal nii, et nad ei kandnud meile liiga ohtrasti sealt vallandunud kiirgussaastet.
The group collaborates tightly with the Estonian Radiation Centre, participates in many international programmes, has assisted in drafting the Estonian radiation legislature, and participates in the training of students in the radioecology and radiation protection. 
Koostööd tehakse Eesti Kiirguskeskusega, võetakse osa paljudest rahvusvahelistest (sh Euroopa Liidu) programmidest, aidati koostada Eesti kiirgusseadusandlust, osaletakse radioökoloogia ja kiirguskaitse õpetamisel.

Irradiation is influencing upon an object with radiation. 
Kiiritus on objekti mõjutamine kiirgusega.
In difference with the visible light, these radiations are invisible, their fluxes can be revealed only by artificial sensors. 
Erinevalt nähtavast valgusest on need kiirgused nähtamatud-aistitamatud, nende vooge saab kindlaks teha üksnes tehistajurite abil.
The group of irradiation physics investigates radiation effects upon solids, mainly ionic crystals (such as common salt, NaCl) and metal oxides (such as unslaked lime, CaO), but also upon much more complicated compounds, e.g. MgAl2O4, Y3Al5O12, BaMgAl10O17. 
Kiiritus- füüsika rühmas uuritakse kiirguste toimet tah- kistele, peamiselt ioonkristallidele (nagu keedusool, NaCl) ja metallioksiididele (nagu kustutamata lubi, CaO), kuid ka sootuks keerukamatele ühenditele, nt. MgAl2O4, Y3Al5O12, BaMgAl10O17.
In crystals the atoms are packed into a regular crystal lattice, where the structure elements are repeated many times, as bricks in a wall. 
Kristallides on aatomid paigutunud korrapärasesse kristallivõresse, millele on omane struktuurielementide korduvus, otsekui tellisseinas.
Under the influence of radiation several solids shine light or emit luminescence, their absorption spectrum and electrical conductivity change, and, what is especially significant, the hard radiations “shake up” their crystal lattice. 
Kiirguste toimel hakkavad paljud tahkised he- lendama e luminestseerima, muutub nende neeldumisspekter ning elektrijuhtivus, ja mis eriti oluline: kalgid kiirgused “raputavad segamini” nende kristallivõre.
This, in order, leads to the modification of the absorption spectrum, in its optical part as well as in the region of radio frequencies. 
Sellest ka neeldumisspektri teisenemine, seda nii spektri optilises kui ka raadiokiirguse piirkonnas.
(In the last case the spectra of electron spin resonance, briefly ESR are detected.) 
(Viimasel juhul mõõdetakse elektroonse paramagnetilise resonantsi, lühidalt EPR spektreid.)
The emission spectrum becomes also changed. 
Muutumata ei jää ka kristalli helendusspekter.
From one side, the research of irradiation physics belongs to fundamental physics: it gives new information abot the atomic structure of solids and its conversions under radiataion, and about the excitation states, migrating about in the crystal lattice – uncharged excitons, conduction electrons and -holes etc. 
Ühtpidi kuuluvad kiiritusfüüsika uurimised alus- füüsikasse: nad annavad uusi teadmisi ainete aatomstruktuurist ja selle muundeist kiirituse all, kristallivõres rändavatest ergastusseisundi- test – laenguta eksitonidest, juhtivuselektro- nidest ja -aukudest jpm.
On the other hand, the irradiation physics has high applied value, elucidating radiation sensitive as well as radiation resistant materials. 
Teisalt on kiiritusfüüsikal oluline rakenduslik tähtsus, sest ta aitab välja selgitada nii kiiritus- tundlikke kui ka kiirituskindlaid materjale.
The first ones are needed to fabricate radiation sensors and dosimeters. 
Esimesi vajatakse kiiritusannuse mõõturite – dosimeetrite ja kiirgustajurite valmistamiseks.
The second ones are needed in nuclear energetics, luminescent lamps, laser irradiatiors, details of laser optics etc. 
Teisi on tarvis nt tuumaenergeetika seadisteks, lumi- nestsentskiirguriteks, laserikiirguriteks, laserop- tikaks jne.
The main caharacteristic features of the investigations of the group are: selection of the experimental objects, wide variability of the experimental conditions, multisided (systems) approach. 
Rühma uurimistöö eripära seisneb: katseobjektide valikus, katsetingimuste avaras varieeritavuses, süsteemses lähenemisviisis.
They differ from thoroughly examined semiconductors by a wide band gap (or forbidden band). 
Neid eristab seni laialt uuritud pooljuhtidest lai keelutsoon.
Such materials are usable even at temperatures, considerably higher than the room temperature. 
Sellised ained on töökõlblikud ka toatemperatuuri tunduvalt ületavas kuumuses.
As to the experimental conditions, the energy of influencing quanta or electrons can be varied in wide limits (from X ray region to infrared dia- pason, energy of electrons from some electron volt to the energies characteristic to the accelerators, 300 keV), temperature of the object (from the cold near absolute zero up to temperatures of incandescence), pressure of the ambient gas from an ultra high vacuum up to normal conditions etc. 
Katsetingimustest on võimalik laiades piirides varieerida mõjuvate kvantide või elektronide energiat (lainepikkust röntgenialast infrapunani, elektronide energiat mõnest elektronvoldist kiirendienergiateni 300 keV), objekti temperatuuri (absoluutnulli lähistelt hõõgkuumuseni), ümbritseva gaasi rõhku ülivaakumist normaalrõhuni jne.
The laboratory of X-ray spectroscopy, belonging to the group, carries out investigations on the frontier of atomic physics and solid state physics, uncovering the processes, encompassing cores of the crystal-forming atoms, e.g. creation of relatively high energy electron excitations – X ray excitons. 
Rühma kuuluv röntgenspektroskoopia labor teeb sünk- rotronkiirgust kasutades uurimisi aatomifüüsika ja tahkisefüüsika piirimail, selgitades kiiritamisel kristallides toimuvaid protsesse, nt suure energiaga elektronergastuste – röntgeneksitonide teket kristallides.
Besides the visible and invisible emissions significant additional information on the objects is obtained from the electron spectra – energy distributions of the electrons, emitted from an irradiated solid. 
Objektide nähtava ja nähtamatu helenduse kõrval saadakse olulist lisateavet objektide kohta kiiritatavast ainest paiskuvate elektronide energiajaotusest– elektronspektrist.
Just now at the Institute is established a new laboratory, that of the electron spectroscopy. 
Praegu on instituudis teoksil uue, elektronspektroskoopia labori rajamine.
A contemporary electron spectrometer, Gamma- data-Scienta SES100 has already arrived. 
Kaasaegne elektronspektro- meeter Gammadata-Scienta SES100 on juba ootel.
The phenomena, discovered former by the group members, the photon multiplicationand transformation of electron excitations into lattice defects, are now futher examined in detail. 
Uuritakse süvitsi varasematel aastatel rühma liikmete avastatud nähtusi: footonite paljune- mistja elektronergastuste võredefektideks muundumist.
The dosimeters just in use are not bioequivalent. 
Seni käibel olevad dosimeetrid ei ole bioekvivalentsed.
Radiation proof materials are needed, among other demands, for the crystal optics, applicable in the beams of ultraviolet lasers: under certain circumstances laser radiation also wrecks a crystal lattice. 
Kiirituskindlaid materjale läheb vaja nt ultarvio- lettlaserite kimpudes kasutatava optika jaoks, sest ka laserikiirgus on teatud tingimustel tugevasti kristallivõret laostav.
The results, gained in tight collaboration with Czech and Italian physicists are in use by some European enterprises, fabricating sensitive radiation sensors (scintillation counters), used also in the medical diagnostics – in the computer tomographs. 
Rühma liikmete ning Tšehhi ja Itaalia füüsikute tihedas koostöös saadud tulemused on leidnud kasutamist Euroopa ettevõtetes ülitundlike kiir- gustajurite (stsintillatsioonloendurite) valmistamisel, mis ms leiavad rakendust meditsiinilises diagnostikas – kompuutertomograafides.
