In the bustling halls of the Harare Institute of Public Health, a young woman is proving that one innovative idea can protect countless lives. Charity Jonasi, a biomedical engineering student, has developed a breakthrough solution that promises to make healthcare safer for both patients and medical workers across Zimbabwe and beyond.

Growing up, Charity witnessed the real-world consequences of gaps in healthcare systems. Rather than feeling discouraged, those experiences ignited a passion within her to pursue biomedical engineering, a field where technical skill directly translates into saving lives. Today, she's channeling that passion into something remarkable: a low-cost, automated X-ray interlock system designed specifically for small and under-resourced health centers.

The problem Charity identified is both serious and widespread. In many medical facilities, X-ray rooms operate without proper safety interlock systems, often because conventional equipment is prohibitively expensive or technical support is scarce. This means radiation machines can sometimes be activated while doors remain open or unauthorized individuals are present, creating dangerous exposure risks. Charity's innovative system ensures radiation is released only when all safety conditions are properly met, protecting everyone from genetic damage, radiation-related cancers like leukemia, and other serious health complications.

"Engineering is not just about solving problems," Charity explains with genuine warmth. "It is about serving people." That philosophy shines through every aspect of her work.

The Ripple Effect

What makes Charity's achievement even more inspiring is the broader impact it represents. By creating an affordable alternative to expensive safety equipment, she's opening doors for smaller clinics and rural health centers that previously couldn't afford adequate protection. Her innovation means pregnant women receiving X-rays can do so with greater peace of mind, healthcare workers can perform their duties without accumulating dangerous radiation exposure, and facilities can meet international safety standards without breaking their budgets.

The supportive environment at the Harare Institute of Public Health provided Charity with mentorship and hands-on training that helped transform her concept into a working reality. She's since shared her project, titled Safety from Radiation Exposure, on the Health Shenanigans Podcast, where she advocated for stronger cross-sector collaboration to support sustainable healthcare innovation.

As a woman entering a traditionally male-dominated technical field, Charity has faced her share of challenges, from being underestimated to navigating spaces with few female role models. Yet she chose to respond by deepening her expertise and confidently claiming her place in innovation spaces. The experience, she reflects, has actually become a source of strength rather than limitation.

Today, Charity's journey stands as a beacon of what's possible when young women are supported to innovate in fields critical to national development. She believes deeply that when girls invest in education, confidence, and courage, they don't just transform their own futures but create pathways for others to follow. Her work proves that technical innovation combined with genuine compassion can create solutions that truly serve communities, one safer X-ray room at a time.
