TLDR
Research in Ramsar, a northern coastal city of Iran, has some high level natural radiation areas (HLNRAs) as well as over 50 hot springs with low and high radium contents used as spas by the public and vacationers, and shows significant increase of CD69 expression on TCD4+ stimulated cells and total serum IgE and higher incidence of stable and unstable chromosomal aberrations in the HLNRA group compared to the control group with normal background radiation.About:

ICRP PUBLICATION 118: ICRP Statement on Tissue Reactions and Early and Late Effects of Radiation in Normal Tissues and Organs – Threshold Doses for Tissue Reactions in a Radiation Protection Context
F A Stewart,A V Akleyev,Martin Hauer-Jensen,Jolyon H Hendry,N J Kleiman,Thomas J. MacVittie,B M Aleman,Angela B. Edgar,K Mabuchi,C R Muirhead,Roy E. Shore,William Wallace +11 more
TL;DR: Estimates of ‘practical’ threshold doses for tissue injury defined at the level of 1% incidence are provided and it appears that the rate of dose delivery does not modify the low incidence for reactions manifesting very late after low total doses, particularly for cataracts and circulatory disease.
ICRP statement on tissue reactions and early and late effects of radiation in normal tissues and organs -- threshold doses for tissue reactions in a radiation protection context
C. H. Clement,F. A. Stewart +1 more
TL;DR: In this paper, the authors present a statement on the early and late effects of ionising radiation in normal tumor and kidney responses to irradiation, as well as some modifications of normal tumor response.

Human exposure to high natural background radiation: what can it teach us about radiation risks?
Jolyon H Hendry,Steven L. Simon,Andrzej Wojcik,Mehdi Sohrabi,Werner Burkart,Elisabeth Cardis,Dominique Laurier,Margot Tirmarche,Isamu Hayata,Isamu Hayata +9 more
TL;DR: The possible contribution of studies of populations living in high natural background radiation (HNBR) areas (Guarapari, Brazil; Kerala, India; Ramsar, Iran; Yangjiang, China), including radon-prone areas, to low dose risk estimation is reviewed.

Radioadaptive response revisited.
Soile Tapio,Vesna Jacob +1 more
TL;DR: Although adaptive response seems to function by an on/off principle, it is a phenomenon showing a high degree of inter- and intraindividual variability, it remains to be seen to what extent adaptive response is functional in humans at relevant dose and dose-rate exposures.

TL;DR: In this paper, a review of the most effective low-dose radiotherapy treatment schedule and radiobiological mechanisms underlying the anti-inflammatory effects of LD-RT in various in vitro experiments, in vivo studies, and clinical studies is presented.

Cytogenetic investigation in a Brazilian population living in an area of high natural radioactivity.
TL;DR: An increase in the total number of chromosomal aberrations was found in the inhabitants of Guarapari, compared to a control group, indicating possible biological effects of chronic natural radiation exposure.

Exposure to 226Ra from consumption of vegetables in the high level natural radiation area of Ramsar-Iran
TL;DR: The vegetable-to-soil concentration ratio (CR) for (226)Ra and the related effective dose were studied in Talesh Mahalleh, a district of the city of Ramsar in Iran with a high level of natural radiation (HLNR).

Chromosome Aberration, Cancer Mortality and Hormetic Phenomena among Inhabitants in Areas of High Background Radiation in China
Chen Deqing,Wei Luxin +1 more
TL;DR: The frequencies of chromosome aberration in circulating lymphocytes were examined for persons residing in the high background radiation areas (HBRA) and control areas (CA) and the findings are compatible with the assumption that the lower mortality from cancer in the HBRA is the result of the hormetic effects of the three-fold higher dose rate of background radiation in that areas.
