    Study Notes

    Jabiluka Deposit

    • Jabiluka consists of a pair of uranium deposits and was proposed for development in the Northern Territory of Australia.
    • The deposit is located on land of the Mirarr clan, an Aboriginal group, emphasizing the Indigenous connection to the site.
    • Surrounding the mine site is the Kakadu National Park, a World Heritage site, highlighting its ecological significance.
    • Prime Minister Anthony Albanese announced the extension of Kakadu National Park to include the Jabiluka site, respecting the wishes of the Mirarr people.
    • Archaeological findings near Jabiluka included stone axes and tools, dating back tens of thousands of years, indicating the site's historical importance.
    • Legal disputes between Indigenous custodians and mining companies have historically hindered the development of Jabiluka since its discovery in the 1970s.
    • Jabiluka is recognized as one of the largest unmined high-grade uranium deposits globally, as indicated by the World Nuclear Association.
    • Energy Resources of Australia, a subsidiary of Rio Tinto, previously held mining leases at the Jabiluka site.
    • An incident in 2020 where Rio Tinto destroyed ancient rock shelters in Juukan Gorge intensified scrutiny over the conservation of Indigenous heritage sites in Australia.
    • The conservative opposition in Australia aims to build nuclear power plants if they win the next election, challenging a 26-year nuclear ban.

    WazirX

    • WazirX, often marketed as "India Ka Bitcoin Exchange," is a major crypto exchange based in Mumbai.
    • The platform halted withdrawals following a major hacking incident, raising security concerns.
    • It is one of the few crypto exchanges in India registered with the Financial Intelligence Unit (FIU), enhancing its legitimacy.
    • A security breach identified as a “force majeure event” resulted in a significant loss of approximately $230 million.
    • WazirX indicated they have taken steps to block deposits and engage with relevant wallets to recover lost funds.
    • Issues arose due to discrepancies between the displayed data on Liminal's interface during the cyber attack and the actual transactions.
    • Historical contributions to uranium research highlight figures like Eugène-Melchior Péligot, who isolated uranium, and Henri Becquerel, who discovered its radioactive properties.
    • Notable nuclear advancements were propelled by researchers Otto Hahn, Lise Meitner, and J. Robert Oppenheimer, particularly in military and energy applications.
    • The Cold War era witnessed an arms race resulting in a vast stockpile of nuclear weapons using uranium.
    • Nuclear disarmament programs involve significant expenditures for dismantling weapons and related facilities.
    • Uranium is still utilized in modern nuclear reactors as a CO2-free energy source, although it poses future waste management challenges due to its radioactive nature.

    Uranium in the Environment

    • Uranium is a global health concern stemming from both natural and anthropogenic sources.
    • Natural radioactivity levels of uranium are generally low, yet its chemical toxicity can affect various body systems, particularly the kidneys.
    • Activities such as mining and nuclear power contribute to uranium contamination in the environment.
    • The biological half-life of uranium is approximately 15 days, indicating how long it stays in the human body.
    • The use of depleted uranium in military applications is contentious due to potential long-term health implications.
    • The existence of nuclear waste from power plants is a critical concern for public health and environmental safety, necessitating effective waste management strategies.
