How long does it take light to travel from Sun to the Earth

The Earth is 93 million miles (150 million kilometers) away from the Sun. It is average distance because Earth orbit is elliptical. The speed of light in a vacuum is 300,000 km/s so the light travel approximately about 8 minutes (more exactly: 499 seconds)
Iodine123 Half-Life

The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The half-Life of Iodine123 is about 13.1 hour.
