Background There is still uncertainty on whether ionizing radiation from CT scans can
increase the risks of cancer. This study aimed to identify the association of cumulative …

Background The detrimental health effects associated with the receipt of moderate (0.1–1
Gy) and high (> 1 Gy) acute doses of sparsely ionising radiation are well established from …

INTRODUCTION The 1986 Chernobyl (Chornobyl in Ukrainian) nuclear power plant
accident exposed millions of individuals in the surrounding region to radioactive …

Objective To evaluate the effect of protracted low dose, low dose rate exposure to ionising
radiation on the risk of cancer. Design Multinational cohort study. Setting Cohorts of workers …

Summary Background The European EPI-CT study aims to quantify cancer risks from CT
examinations of children and young adults. Here, we assess the risk of brain cancer …

Abstract The International Commission on Radiological Protection (ICRP) has embarked on
a review and revision of the system of Radiological Protection that will update the 2007 …

Recent studies suggest that every year worldwide about a million patients might be exposed
to doses of the order of 100 mGy of low-LET radiation, due to recurrent application of …

Despite decades of research to understand the biological effects of ionising radiation, there
is still much uncertainty over the role of dose rate. Motivated by a virtual workshop on the …

20 years ago, 3 manuscripts describing doses and potential cancer risks from CT scans in
children raised awareness of a growing public health problem. We reviewed the …

Background: Estimates of radiation risks following prolonged exposures at low doses and
low-dose rates are uncertain. Medical radiation workers are a major component of the …
