“…Recently, there has been an increasing necessity for more precise prediction and measurement of aviation radiation in Korea. In the interest of ensuring the radiation safety of our aircrew and passengers, KASI and the Korea Meteorological Administration-National Meteorological Satellite Center (KNMSC) jointly developed their own radiation prediction model, named the Korean Radiation Exposure Assessment Model for the aviation route dose (KREAM) (Hwang et al 2010(Hwang et al , 2014. KREAM is a physicsbased aviation radiation dose calculation program designed for altitudes of 0-80 km that incorporates physical models such as GEANT4 and NRLMSIS00 and a cutoff rigidity model (refer to Fig.…”

The Korean heliospheric community, led by the Korea Astronomy and Space Science Institute (KASI), is currently assessing the viability of deploying a spacecraft at the Sun-Earth Lagrange Point L4 in collaboration with National Aeronautics and Space Administration (NASA). The aim of this mission is to utilize a combination of remote sensing and in situ instruments for comprehensive observations, complementing the capabilities of the L1 and L5 observatories. The paper outlines long-term scientific objectives, underscoring the significance of multi-point in-situ observations to better understand critical heliospheric phenomena. These include coronal mass ejections, magnetic flux ropes, heliospheric current sheets, kinetic waves and instabilities, suprathermal electrons and solar energetic particle events, as well as remote detection of solar radiation phenomena. Furthermore, the mission’s significance in advancing space weather prediction and space radiation exposure assessment models through the integration of L4 observations is discussed. This article is concluded with an emphasis on the potential of L4 observations to propel advancements in heliospheric science.

“…In Korea, the Ambient Radiation Safety Control Act came into effect in July 2012, and the airline where the patient was employed launched to record the radiation dose using CARI-6M for flight crews since 2008. 16 The CARI-6M, a software developed by the US federal aviation administration, calculates the effective dose of cosmic radiation exposure to an individual on an aircraft flying a user-specified route. However, the routes beyond the Korean domestic area are also considered when calculating cosmic radiation with CARI-6M.…”

Background Some epidemiological studies have estimated exposure among flight attendants with and without breast cancer. However, it is difficult to find a quantitative evaluation of occupational exposure factors related to cancer development individually in the case of breast cancer in flight attendants. That is, most, if not all, epidemiological studies of breast cancer in flight attendants with quantitative exposure estimates have estimated exposure in the absence of individual flight history data. Case presentation A 41-year-old woman visited the hospital due to a left breast mass after a regular check-up. Breast cancer was suspected on ultrasonography. Following core biopsy, she underwent various imaging modalities. She was diagnosed invasive ductal carcinoma of no special type (estrogen receptor positive in 90%, progesterone receptor positive in 3%, human epidermal growth factor receptor 2/neu equivocal) with histologic grade 3 and nuclear grade 3 in the left breast. Neoadjuvant chemotherapy was administered to reduce the tumor size before surgery. However, due to serious chemotherapy side effects, the patient opted for alternative and integrative therapies. She joined the airline in January, 1996. Out of all flights, international flights and night flights accounted for 94.9% and 26.2, respectively. Night flights were conducted at least four times per month. Moreover, based on the virtual computer program CARI-6M, the estimated dose of cosmic radiation exposure was 78.81 mSv. There were no other personal triggers or family history of breast cancer. Conclusions This case report shows that the potentially causal relationship between occupational harmful factors and the incidence of breast cancer may become more pronounced when night shift workers who work continuously are exposed to cosmic ionizing radiation. Therefore, close attention and efforts are needed to adjust night shift work schedules and regulate cosmic ionizing radiation exposure.

“…The model is based on measurements taken on board Concorde flights during GLEs in 1989 and 2000 and gives reasonable estimates of dose exposure (Lantos & Fuller, 2004). The KREAM model uses a Monte‐Carlo code (GEANT4) to handle all the physical processes a particle would undergo when passing through a material (Hwang et al., 2014). KREAM has been evaluated with NAIRAS version 2.0 and CARI‐6M and compared with Liulin observations.…”

Exposure to ionizing radiation from galactic cosmic rays (GCR) and solar energetic particles (SEP) at aircraft flight altitudes can have an adverse effect on human health. Although airline crews are classified as radiation workers by the International Commission on Radiological Protection (ICRP), in most countries, their level of exposure is unquantified and undocumented throughout the duration of their career. As such, there is a need to assess pilot ionizing radiation exposure. The Nowcast of Aerospace Ionizing RAdiation System (NAIRAS), a real‐time, global, physics‐based model is used to assess such exposure. The Automated Radiation Measurements for Aerospace Safety (ARMAS) measurement data set consists of high latitude, high altitude, and long‐duration aircraft flights between 2013 and 2023. Here, we characterize radiation exposure at aviation flight altitudes using the NAIRAS model and compare with 45 flight trajectories from the recent ARMAS flight measurement inventory.
