How Röntgen accidentally discovered x-rays & changed the world

Note4Students

From UPSC perspective, the following things are important :

Prelims level: X-ray applications;

Mains level: Biotechnology; Issues related to Health care Machines;

Why in the News?

On the evening of November 8, 1895, Wilhelm Conrad Röntgen was conducting experiments in his laboratory at the University of Würzburg in Germany when he made an unusual discovery.

 

Did you know the Röntgen’s discovery story of X-rays?

  • While experimenting with cathode rays in a glass vacuum tube, Röntgen noticed a fluorescent screen glowing at a distance, despite being too far to be affected by the rays he was studying.
  • Intrigued by this unexpected glow, he wondered if this mysterious ray could penetrate organic materials, so he experimented by photographing his wife’s hand, capturing her bones and ring. This was the world’s first recorded X-ray image of the human body.
  • Röntgen documented his findings in an article titled “On a new kind of rays,” in 1895 which was published by introducing “X-rays” to the scientific community.

How did Röntgen’s discovery transform Medical practices and Diagnostics?

  • Revolution in Diagnostic Medicine: Physicians rapidly adopted X-rays, which allowed them to view the human body without surgery. This was transformative for diagnostics, especially in orthopedics and internal medicine.
  • Surgical Advancements: By February 1896, British physician Major John Hall-Edwards had successfully used X-rays to guide the surgery. Within months, armies began using X-ray technology to locate bullet wounds and diagnose fractures, marking the beginning of its use in trauma care.

What are the long-term implications of Röntgen’s discovery on Public health and Safety?

  • Development of Radiology: this discovery led to the birth of radiology, with subsequent advancements leading to CT, MRI, ultrasound, and other imaging technologies that are essential in modern medicine.
  • Radiation Safety and Awareness: Initially, x-rays were used liberally, even for non-medical purposes (such as in shoe stores to fit footwear), with little awareness of potential harm. It wasn’t until early reports of radiation burns and later research in the early 20th century that the health risks of radiation exposure were acknowledged, prompting the development of safety protocols.
  • Ongoing Safety Protocols: Today, radiation safety is central to radiology practices. Equipment advancements and regulatory standards have minimized exposure risks, making x-rays safe for patients and medical personnel while ensuring their continued benefits.
  • Public Health and Preventive Care: The ability to detect diseases, fractures, and other internal injuries without invasive procedures has been crucial for preventive care, enabling early detection and treatment. This has significantly impacted patient survival rates and quality of care, solidifying diagnostic imaging as a pillar of modern public health.

Issues related to X-ray machines in Rural areas:

  • Limited X-ray Equipment: Rural Community Health Centres (CHCs) in India often need more X-ray machines, with only 68% of available units functioning, primarily due to high operational costs and shortages of technicians.
  • Maintenance and Operational Delays: Even when X-ray machines are present, many remain non-functional due to installation delays and insufficient maintenance, as imaging services are not prioritized in CHC guidelines.
  • Access and Specialist Shortages: Rural patients face long travel distances to access imaging services, further limited by a concentration of radiologists in urban areas, reducing timely access to diagnostic interpretation.

Way forward: 

  • Strengthen Infrastructure and Access: Increase the availability and functionality of X-ray machines in rural areas by improving equipment maintenance, investing in portable and mobile X-ray units to bring diagnostic services directly to underserved populations.
    • For example, Teleradiology enables remote interpretation of images, improving access to diagnostic services.
  • Telemedicine and Remote Diagnostics: Expand telemedicine platforms like ‘XraySetu’, enabling healthcare workers in rural areas to share X-ray images for remote analysis by radiologists, improving diagnostic capabilities without requiring patients to travel long distances.

Minority Issues – SC, ST, Dalits, OBC, Reservations, etc.

SC overrules 1967 verdict on AMU’s minority tag

Note4Students

From UPSC perspective, the following things are important :

Mains level: Judiciary; Landmark Judgements; Issues related to Minority status;

Why in the News?

In a 4:3 majority decision, the Supreme Court overturned its 1967 Azeez Basha ruling, which had denied Aligarh Muslim University (AMU) minority status, directing that AMU’s status be reassessed according to the principles outlined in the current judgment.

Constitutional Provisions and Historical Background of the case:

  • The Aligarh Muslim University (AMU) was founded in 1875 and incorporated by imperial law in 1920.
  • Article 30 of the Constitution empowers religious and linguistic minorities to establish and administer educational institutions – AMU had enjoyed minority status.
  • A 1951 amendment to that imperial law, the AMU Act, did away with compulsory religious instructions for Muslim students.
  • In India, compulsory religious instruction is prohibited in state-funded educational institutions under Article 28.
  • In S. Azeez Basha vs. Union of India (1967), the SC ruled that AMU could not be considered a minority institution, as it was established by a central act, categorizing it as a central university.
    • This ruling denied AMU the rights of minority institutions under Article 30 of the Indian Constitution.
  • In 1981, an amendment to the AMU Act attempted to restore AMU’s minority character, aiming to secure rights for it as a minority-administered institution.
  • The Allahabad High Court (2006) struck down the 1981 amendment, reinforcing the Supreme Court’s earlier ruling and reasserting that AMU did not qualify as a minority institution.

 

What criteria will be used to assess AMU’s minority status?

  • The SC emphasized that an educational institution must be established by a minority community to qualify for minority status under Article 30(1) of the Indian Constitution.
    • This involves examining who initiated the idea of the institution and whether it was primarily intended to benefit that community.
  • Holistic Two-Fold Test: The Court introduced a two-fold test:
    • First Limb: Identify the “brain behind” the establishment, which includes reviewing correspondence and documentation that reflect the intentions of the founders.
    • Second Limb: Assess whether the administrative structure of the institution affirms its minority character and serves to protect and promote the interests of the minority community.
  • Broad Interpretation of “Established”: The ruling clarified that “established” should be interpreted broadly, meaning that an institution can still be considered a minority institution even if it is governed by a statutory body or has undergone changes in its legal status over time.

How does this ruling affect the legal precedent set by the 1967 Azeez Basha case?

  • The overruling of Azeez Basha: The SC’s decision effectively overruled its previous 1967 ruling, which had declared AMU as not being a minority institution because it was established through a government statute rather than directly by a minority community.
  • New Framework for Minority Status: This ruling marks a shift towards a more inclusive interpretation of what constitutes a minority institution, allowing for a reassessment of AMU’s status based on historical context and community intent rather than solely on formal legal definitions.
  • Legal Autonomy Reaffirmed: The judgment underscores that legislative recognition does not negate an institution’s minority character, challenging previous interpretations that linked statutory establishment with loss of minority status.

What are the implications of this ruling for Educational rights and Reservations?

  • Potential for Reservations: If AMU is recognized as a minority institution, it could reserve seats specifically for Muslim students in various programs without needing to adhere to general reservation policies applicable to Scheduled Castes (SC), Scheduled Tribes (ST), and Other Backward Classes (OBC) under Article 15(5) of the Constitution.
  • Autonomy in Administration: The ruling provides AMU greater autonomy in managing its affairs, including admissions and staff appointments, thereby allowing it to align its policies with the interests of the Muslim community it serves.
  • Broader Educational Rights: This decision reinforces the constitutional rights granted to minorities under Article 30(1), ensuring that they can establish and administer educational institutions without undue interference from state laws, thereby promoting educational diversity in India.

Way forward: 

  • Define Minority Status Framework: Parliament could establish a clear legislative framework based on the Supreme Court’s criteria, ensuring consistent and streamlined recognition of minority institutions across India.
  • Balance Autonomy and Accountability: Policies should support minority institutions’ autonomy while maintaining accountability to uphold educational standards, ensuring both community-focused goals and inclusive, high-quality education.
