“…Radioactivity is a huge threat to humans and the environment due to its easy diffusion ( Ojovan and Lee, 2011 ; Mowry et al, 2015 ; Yang et al, 2018 ; Chabauty et al, 2019 ). Among these radioactive elements, iodine compounds attract special attention because the iodine is concentrated in the thyroid, and its higher radioactivity can cause damage to the human body in a short time ( Grossman et al, 1996 ; Goldsmith et al, 1999 ; Grossman et al, 2002 ; 2003 ; Lee et al, 2006 ; Thomas et al, 2009 ; Sava et al, 2013 ). The radioactivity is produced by 129 I, a long-period isotope with a half-life of 1.57 × 10 7 years ( Taylor, 1981 ; Michel et al, 2005 ; Zhang et al, 2011 ; Lin et al, 2019 ), and 131 I, a short-lived isotope with a half-life of approximately 8.02 days ( Thomas et al, 2009 ; Lee et al, 2018 ).…”
