Brazil's refusal to allow the Inter-national Atomic Energy Agency (IAEA) to fully inspect one of its nuclear facilities has heightened suspicions about its commitment to nonproliferation.
Although Brazil signed the Nuclear Nonproliferation Treaty in 1997 and said its nuclear program has peaceful objectives, suspicions over its commitment have simmered for more than a year.
They came to a head last week after the government confirmed that IAEA inspectors were denied access in February and last month to uranium-enrichment centrifuges at a facility under construction in Resende, near Rio de Janeiro.

It cited the need to protect industrial secrets and said the centrifuges were, and will remain, off limits for visual inspection.
Science and Technology Minister Eduardo Campos said that Brazil had invested close to US$1 billion and years of research to develop its enrichment technology.
He said the performance of Brazilian centrifuges was 30 percent more efficient than those found in other countries.
"This is a technology we must protect," he said.
Centrifuges are used to enrich uranium for use in nuclear power plants or atomic weapons.
The doubts over Brazil's nuclear program were likely discussed during two days of closed-door meetings between Brazilian officials and the US Assistant Secretary of State for Nonproliferation, John Wolf.
Wolf left Brasilia on Thursday after two days of meetings of the Brazil-US Joint Committee on Nuclear Energy Cooperation.
Brazil's uranium-enrichment program may be discussed next week during a visit by US Energy Secretary Spencer Abraham.
When he arrived Friday in Rio de Janiero, Abraham said, "I don't want to leave the impression that the US and Brazil are not concerned about dirty bombs and terrorism. But I will not speculate on what topics will come up in my conversations with Brazilian officials."
According to the US State Department, those meetings should not be considered the result of "a reaction nor an expression of concern about Brazil's commitment to nuclear nonproliferation," said embassy spokesman Wesley Carrington.
But experts think concerns do exist over Brazil's commitment to nonproliferation.
"Brazil is beginning to be perceived as a country apparently wanting to reevaluate its commitment to nonproliferation and this is a big part of the problem at hand," said Jon Wolfsthal, deputy director for nonproliferation at the Carnegie Endowment for International Peace in Washington.
Its refusal to allow the inspections came "in the middle of Iran's and North Korea's challenges to the IAEA's authority," Wolfsthal said.
"Anything seen as undermining the IAEA's authority puts everyone on edge,'' he said.
Brazil's claim of protecting industrial secrets does not hold up because the IAEA has a "proven track record" of respecting such information.
Brazil's government laid plans for the development of nuclear weapons technologies in the 1970s when the country was governed by a military dictatorship whose leaders were oriented by a stern "national security" doctrine and a traditional rivalry with Argentina, which was also developing similar technologies during its military regime. But the plans were abandoned when Brazil returned to democracy in the 1980s.
Suspicions about the nuclear program started months before Luiz Inacio Lula da Silva became president in January, 2003.
"Why should we be asked to use slingshots while others point their cannons at us. Brazil will only be respected when it is strong economically, technologically and militarily," Silva said about the Nonproliferation Treaty.
Six weeks later, as president-elect, Silva said his government would never consider building an atomic bomb and respect the treaty.
Worries that Brazil's technology could fall into the wrong hands has also stoked international fears.
Brazil has the world's sixth-largest uranium reserve and has had the capacity to enrich uranium since the 1980s, but has so far only done so for research purposes.
By 2027, Denmark would relocate its foreign convicts to a prison in Kosovo under a 200-million-euro (US$228.6 million) agreement that has raised concerns among non-governmental organizations (NGOs) and residents, but which could serve as a model for the rest of the EU. The agreement, reached in 2022 and ratified by Kosovar lawmakers last year, provides for the reception of up to 300 foreign prisoners sentenced in Denmark. They must not have been convicted of terrorism or war crimes, or have a mental condition or terminal disease. Once their sentence is completed in Kosovan, they would be deported to their home country. In
Brazil, the world’s largest Roman Catholic country, saw its Catholic population decline further in 2022, while evangelical Christians and those with no religion continued to rise, census data released on Friday by the Brazilian Institute of Geography and Statistics (IBGE) showed. The census indicated that Brazil had 100.2 million Roman Catholics in 2022, accounting for 56.7 percent of the population, down from 65.1 percent or 105.4 million recorded in the 2010 census. Meanwhile, the share of evangelical Christians rose to 26.9 percent last year, up from 21.6 percent in 2010, adding 12 million followers to reach 47.4 million — the highest figure
A Chinese scientist was arrested while arriving in the US at Detroit airport, the second case in days involving the alleged smuggling of biological material, authorities said on Monday. The scientist is accused of shipping biological material months ago to staff at a laboratory at the University of Michigan. The FBI, in a court filing, described it as material related to certain worms and requires a government permit. “The guidelines for importing biological materials into the US for research purposes are stringent, but clear, and actions like this undermine the legitimate work of other visiting scholars,” said John Nowak, who leads field
LOST CONTACT: The mission carried payloads from Japan, the US and Taiwan’s National Central University, including a deep space radiation probe, ispace said Japanese company ispace said its uncrewed moon lander likely crashed onto the moon’s surface during its lunar touchdown attempt yesterday, marking another failure two years after its unsuccessful inaugural mission. Tokyo-based ispace had hoped to join US firms Intuitive Machines and Firefly Aerospace as companies that have accomplished commercial landings amid a global race for the moon, which includes state-run missions from China and India. A successful mission would have made ispace the first company outside the US to achieve a moon landing. Resilience, ispace’s second lunar lander, could not decelerate fast enough as it approached the moon, and the company has
