The Linear Non-Threshold (LNT) process is used by virtually all governmental agencies to compute incidence of cancer as a consequence of exposure to a carcinogen. This comment applies the concept of Best Available Science (BAS) Metrics for Evaluation of Scientific Claims (MESC) derived from BAS to issues related to reliability of LNT hypothesis. This paper identifies the level of maturity of the LNT hypothesis and the associated uncertainties.

Purpose: Radiation exposures do not seem to increase the proportion of mice dying from tumors, but rather cause a shift in the appearance of spontaneous cancers, allowing them to appear earlier, and hence produce a life shortening effect. Then, it was possible to estimate the effect of the dose rate on the carcinogenic effects of radiation using life shortening effects as a measure.
Conclusion: The dose response for the induction of life shortening was linear under acute exposure conditions, which indicates that the response under chronic exposure conditions is also likely to be linear, and hence the dose rate factor (DRF) would be constant throughout the dose.

Effectively capturing the risk of air pollution and informing residents is vital to public health. The widely used Air Quality Index (AQI) has been criticized for failing to accurately represent the non-threshold linear relationship between air pollution and health outcomes. Although the Air Quality Health Index (AQHI) was developed to address these limitations, it lacks comprehensive construction criteria.

A newly discovered letter written by Hermann J. Muller in August 1948, reveals that he claimed to have evidence that multiple papers by Frederick Hanson and Florence Heys, including those that supported the linear non-threshold (LNT) dose response model for hereditary and cancer risk assessment, were fraudulent and thus untrustworthy. Muller failed to bring this issue, which he referred to as a major scientific scandal, to the attention of the scientific community, remaining silent for the remainder of his career.

Exposure to ambient ozone (O) is linked to increased mortality risks from various diseases, but epidemiological investigations delving into its potential implications for cancer mortality are limited. We aimed to examine the association between short-term O exposure and site-specific cancer mortality and investigate vulnerable subgroups in Brazil. In total 3,459,826 cancer death records from 5570 Brazilian municipalities between 2000 and 2019, were included.
