To calculate this,

We know that energy is 1 photon
E = hc/wavelenth
wavelength of 10.0 m

Solution:
h = 6.626 x 10^-34 Jsec
C = 2.9979 x 10^8 m/sec
E = 6.626 10^-34 * 2.9979 10^8 / 10 = 1.9864 10^-26J

Then, the number of photons is computed by:

n = 1000 / 1.9864 10^-26 = 5.04 10^28 photons

Explanation:

So basically is just explain what radioacitvity and then radidoactive

Radioactivity is the spontaneous release of energy from an unstable atom to get to a more stable state. Ionizing Radiation is the energy that comes out of a radioactive atom. Radioactive isotopes are radioactive atoms of the same element that have different numbers of neutrons.
