T-D-S formula I learned decades ago useful now in Covid19 risk reductionLearning never goes useless. If we know how to recall and apply it becomes very much worthy.
Immediately after my science graduation, I joined an important and famous Research Centre in our country. I was associated with a Project where radioactive materials were handled.
Very initially itself we were briefed about the safety precautions to prevent or reduce the radioactive material contamination and radiation. We were taught the T-D-S formula-(Time Distance Shielding formula.)
The ormula is explained as follows:
T- One should have full details of the work to be done and should spend the minimum time at the work spot where radioactivity risk is there.
D-One should keep the maximum distance possible from the radioactive risk source.
S-One should wear prescribed and proper shielding on the body, as per work and risk perception.
It is more than forty years since I left that job. The TDS formula for safety is coming handy for me in the Corona risk prevention. How TDS applies here?
One should keep minimum time at public places and where the infection risk is there. One should keep the maximum possible distance from another person. One should wear proper shielding like a proper face mask, even face shield, etc.
Safety first anytime anywhere.
