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.
