Dose distribution of 131I, 132I, 133I, 134I, and 135I due to a hypothetical accident of TRIGA Mark-II research reactor.

Abstract

An attempt has been made in the work to assess radiological dose due to the deposition of ¹³¹I, ¹³²I, ¹³³I, ¹³⁴I, and ¹³⁵I on ground, vegetation, milk and meat considering a hypothetical accident of TRIGA Mark-II research reactor at AERE, Savar. Contribution of dose from ingestion of vegetation due to ¹³¹I has been found to be dominant (62.96%). Also found that contribution of ¹³²I from immersion is higher (53.67%) and contribution of ¹³³I in meat is higher (45.64%). The contribution due to ¹³⁴I in both from immersion (46.13%) and from ground deposition (47.19%) was dominant while the contribution of ¹³⁵I from ground deposition (30.11%), inhalation (26.77%) and immersion (25.92%) were higher. Final result says that the vegetation is the dominant contributor (66.91%) for iodine.
